The CDP’s Heritage West database represents not only the primary product of the organization, but also one of the oldest continuously operating collaborative repositories of cultural heritage metadata in the country. As a basis for the author’s forthcoming quantitative and qualitative analysis of Dublin Core metadata in Heritage West, the following article offers a history of how the CDP has, over time, organized and managed the metadata provision for its digitization projects. http://tc.eserver.org/31272.html http://tc.eserver.org/31272.html Firms wrestling with unstructured data such as emails and spreadsheets don't see enterprise content management as the answer to their problems. http://tc.eserver.org/30062.html http://tc.eserver.org/30062.html The recent emergence of online digital archives has brought educators a major step closer to bringing original, reusable digital objects into undergraduate classrooms. Yet having to search multiple archives through mind-numbing search-and-browse routines can make it extremely difficult for educators to use the repositories successfully in their curriculum. What educators need is a suite of tools that allow them to reduce the search for relevance, expand the metadata with user-specific annotation, and tie the digital libraries' content directly to course materials. The keys to creating these resources are to build distributed networks of users and repositories. Cost containment often severely limits the amount of descriptive metadata that can be catalogued. Students and instructors create topical annotated bibliographies or lists of media clips (or segments of media clips) and 'publish' these for class, work group, or more general use. Allowing teachers and students to annotate and segment media as well as build their own galleries greatly enhance the educational value of digital objects by augmenting the minimal descriptive metadata and facilitating the building of complex digital objects tailored to the needs of specific education standards and curricula. The project uses a METS XML schema that provides an encoding format for administrative, descriptive, and structural metadata that is fully compliant with OAIS, and open source applications to facilitate ingestion and delivery (as well as help to control costs). http://tc.eserver.org/30037.html http://tc.eserver.org/30037.html Metadata is structured data which describes the characteristics of a resource. It shares many similar characteristics to the cataloguing that takes place in libraries, museums and archives. The term 'meta' derives from the Greek word denoting a nature of a higher order or more fundamental kind. A metadata record consists of a number of pre-defined elements representing specific attributes of a resource, and each element can have one or more values. http://tc.eserver.org/29575.html http://tc.eserver.org/29575.html This paper examines user-generated metadata as implemented and applied in two web services designed to share and organize digital media to better understand grassroots classification. http://tc.eserver.org/29323.html http://tc.eserver.org/29323.html I was shocked today when I realized I hadn't ever written a post on tagging. At the ASTD TechKnowledge conference, when I explained Web 2.0 to a group, tagging was an integral part of the conversation. But tagging requires you to take a step back from the web, and consider how you think. http://tc.eserver.org/29020.html http://tc.eserver.org/29020.html Work with structured abstracts--which contain sub-headings in a standard order--has suggested that such abstracts contain more information, are of a higher quality, and are easier to search and to read than are traditional abstracts. The aim of this article is to suggest that this work with structured abstracts can be extended to cover scientific articles as a whole. The article outlines a set of sub-headings--drawn from research on academic writing--that can be used to make the presentation of scientific papers easier to read and to write. Twenty published research papers are then analyzed in terms of these sub-headings. The analysis, with some reservations, supports the viability of this approach. http://tc.eserver.org/29172.html http://tc.eserver.org/29172.html An interview with Kevin Shoesmith about information architecture and the challenge of organizing complicated websites. Shoesmith explains about the importance of metadata, providing user-driven organization, taxonomy vs. folksonomy, the Dublin core, the usability of web menus. http://tc.eserver.org/28574.html http://tc.eserver.org/28574.html Metadata from the world of librarians and database searching is moving to center stage in our everyday lives. And the metadata 'revolution' is coming to us through pictures--those cute, happy, funny shots of kids, parents, neighbors and workmates that we love to share and post on the internet. http://tc.eserver.org/28512.html http://tc.eserver.org/28512.html Tag cloud displays tags in a website which emphasize some of the tags by showing them with larger font sizes, and/or in darker colors. Moreover, tags in a tag cloud are usually arranged in alphabetical order. Tag cloud seems to work in the English world as a means of visualization as well as an extra means of navigation - what about in the Chinese world or more specifically, what about in Hong Kong? http://tc.eserver.org/27996.html http://tc.eserver.org/27996.html RDF was originally created in 1999 as a standard on top of XML for encoding metadata--literally, data about data. Metadata is, of course, things like who authored a web page, what date a blog entry was published, etc., information that is in some sense secondary to some other content already on the regular web. Since then, and perhaps especially after the updated RDF spec in 2004, the scope of RDF has really evolved into something greater. The most exciting uses of RDF aren't in encoding information about web resources, but information about and relations between things in the real world: people, places, concepts, etc. http://tc.eserver.org/27325.html http://tc.eserver.org/27325.html In this article, we are going to discuss a major problems involving keyword selection for existing businesses. It is a simple mistake, but one most people do not think about. The two prime Internet marketing platforms are pay-per-click advertising and search engine optimization. The issue we are going to discuss today applies equally to either of these platforms as well as any other internet advertising you undertake. http://tc.eserver.org/27322.html http://tc.eserver.org/27322.html As you have probably heard over and over, keyword research is a pivotal step for success. Taken a step further, it can develop your product lines for you. http://tc.eserver.org/26792.html http://tc.eserver.org/26792.html Libraries must increasingly accommodate bibliographic records encoded with a variety of standards and emerging standards, including Dublin Core, MODS, and VRA Core. The problem is that many libraries still rely solely on MARC and AACR2. Meanwhile, the world of information is passing us by. How important is this problem? There are now literally millions of useful online items that lack MARC cataloging and will likely never be cataloged in MARC. We ignore these resources at our peril. Our users will justifiably seek assistance elsewhere, as many already have. Ignoring the problem will only make libraries increasingly marginalized. What are we to do? http://tc.eserver.org/26179.html http://tc.eserver.org/26179.html The Darwin Information Typing Architecture (DITA) is a hot topic among those who author, edit, deliver and manage content. But adopting a standard architecture is an important decision that requires up front research and knowledge of the pitfalls. Find out if DITA is right for your organization. Read this whitepaper to learn more (PDF). http://tc.eserver.org/26136.html http://tc.eserver.org/26136.html I have long wondered why government web sites all over the world tend to use metadata of several different types jumbled together and overlapping. For example, pages with two description metatags or two or three title tags are common. I suspect that most of the replication and confusion has developed for historical reasons. http://tc.eserver.org/25978.html http://tc.eserver.org/25978.html For all of its upside, XML-based single-source publishing has proven to be expensive and complicated to implement. XML-based single sourcing requires significant tool development, data conversion, and system integration prior to realizing the benefits of repurposing and reuse. To mitigate this, some vertical industries have developed their own XML tag sets. While successful on their own, these vertical industry efforts have not been extensible to other industries. A new XML-based approach to information development is the Darwin Information Typing Architecture (DITA). http://tc.eserver.org/25705.html http://tc.eserver.org/25705.html Many classification systems suffer from an inflexible top-down approach, forcing users to view the world in potentially unfamiliar ways. http://tc.eserver.org/25655.html http://tc.eserver.org/25655.html The Dublin Core is currently the best-developed candidate for a simple resource description model for electronic resources on the Web. It represents the results of a three year process of consensus-building through a series of focussed, invitational workshops involving librarians, digital library researchers, and various content specialists from many countries. http://tc.eserver.org/25494.html http://tc.eserver.org/25494.html The Semantic Web promises to provide new applications for Internet users through the use of RDF metadata attached to various information resources on the web. Yet issomewhat unclear who will provide the metadata, or what will motivate people to provideit, let alone the exact nature of the applications the Semantic Web will ultimately support. What will the ¡°killer app¡± of the Semantic Web be, and what shape will it take? http://tc.eserver.org/23888.html http://tc.eserver.org/23888.html The authors present a new method of image searching based on conceptual descriptors. This method differs from the traditional methods of image searching that are based on keywords and visual similarity. http://tc.eserver.org/23895.html http://tc.eserver.org/23895.html This document of best practices offers assistance in creating metadata records for digitized resources using the Dublin Core element data set. http://tc.eserver.org/23819.html http://tc.eserver.org/23819.html Discusses Christopher Alexander's theories about a group of related design patterns, referred to as a 'pattern language.' http://tc.eserver.org/23599.html http://tc.eserver.org/23599.html DITA is an architecture for creating topicoriented, information-typed content that can be reused and single-sourced in a variety of ways. It is also an architecture for creating new information types and describing new information domains, allowing groups to create very specific, targeted document type definitions using a process called specialization, while at the same time reusing common output transforms and design rules. We discuss several methods that can be used to extend DITA’s basic topic types. http://tc.eserver.org/23254.html http://tc.eserver.org/23254.html L'articolo descrive il funzionamento della Classificazione Bibliografica Bliss, 2a edizione (BC2), sistema di classificazione interamente basato su uno schema a faccette, di cui Vanda Broughton è la curatrice insieme a Jack Mills. http://tc.eserver.org/23253.html http://tc.eserver.org/23253.html Samantha Bailey, formerly at Argus and current lead IA for Wachovia Corporation's Wachovia.com website, talks about the transition from being a consultant to an 'innie' IA, unravels the mysteries of metadata and taxonomies and shares her vision of the future of IA. http://tc.eserver.org/23200.html http://tc.eserver.org/23200.html La classificazione rappresenta un investimento che comporta dei costi nel breve termine, ma che dà anche notevoli frutti nel lungo termine (se impostata correttamente). Fra i sistemi di classificazione, quello a faccette (o multidimensionale) è sicuramente il più potente e versatile (nonostante gli schemi affermatisi come standard nella maggioranza delle biblioteche sono assai distanti da quello a faccette). http://tc.eserver.org/23192.html http://tc.eserver.org/23192.html This article addresses two aspects of classification: innovation and faceted classification. Includes links to additional online resources involving classification. http://tc.eserver.org/23198.html http://tc.eserver.org/23198.html L'articolo fornisce una introduzione al concetto di 'classificazione a faccette', descrivendo: i suoi vantaggi rispetto ai sistemi di classificazione gerarchici; esempi di applicazione al web; un esempio di applicazione alla classificazione dei formaggi. http://tc.eserver.org/23205.html http://tc.eserver.org/23205.html This study discusses the role of classification schemes in resource description and discovery. It recommends automatic classification processes if large robot-generated services are to offer a good browsing structure for their documents or advanced filtering techniques as well as proper query expansion tools to improve the search process. http://tc.eserver.org/23217.html http://tc.eserver.org/23217.html A tutorial on the basics of constructing an information retrieval thesaurus. It includes a glossary of thesaurus terms. http://tc.eserver.org/23115.html http://tc.eserver.org/23115.html In content metadata and hierarchies, you will often find a goldmine of implicit and explicit data that you can leverage to creatively contextualize content. After a brief introduction on taxonomy and metadata, this article focuses on finding and utilizing such relationships in hierarchies. http://tc.eserver.org/23097.html http://tc.eserver.org/23097.html This paper presents 'Distributed Active Relationships' (an extension of the Warwick Framework), a general framework for dealing with meta data issues in digital libraries and other information systems. By treating meta data as data, rather than giving it a special distinguished role, arbitrary resources are allowed to be associated with arbitrary relationships. http://tc.eserver.org/23098.html http://tc.eserver.org/23098.html Automated classification tools can't solve today's large-scale web and intranet indexing challenges alone. Neither can humans. But solutions that integrate human expertise with software products such as Interwoven's Metatagger and Autonomy's Categorizer can provide real value and savings. After a brief introduction to automated classification, this white paper discusses the benefits and limitations of manual, automated, and hybrid approaches. It explores the opportunities for leveraging controlled vocabularies and thesauri to produce more effective indexing solutions. http://tc.eserver.org/22747.html http://tc.eserver.org/22747.html The Semantic Web really is an attempt to reconceptualize and reengineer AI for the Web. Discusses the path forward for successfully selling and developing Semantic Web technology into industry. http://tc.eserver.org/22701.html http://tc.eserver.org/22701.html PRISM is an extensible XML metadata standard for syndicating, aggregating, post-processing and multi-purposing content from magazines, news, catalogs, books and mainstream journals. http://tc.eserver.org/22394.html http://tc.eserver.org/22394.html This paper outlines the assumptions, process and results of a pilot study of issues of interoperability among a set of seven existing controlled vocabulary schemes that make statements about the audience of an educational resource. http://tc.eserver.org/22395.html http://tc.eserver.org/22395.html Knowledge management in digital libraries is a universal problem. Keyword-based searching is applied everywhere no matter whether the resources are indexed databases or full-text Web pages. In keyword matching, the valuable content description and indexing of the metadata, such as the subject descriptors and the classification notations, are merely treated as common keywords to be matched with the user query. Without the support of vocabulary control tools, such as classification systems and thesauri, the intelligent labor of content analysis, description and indexing in metadata production are seriously wasted. http://tc.eserver.org/22393.html http://tc.eserver.org/22393.html Metadata generation is the act of creating or producing metadata. Generating good quality metadata in an efficient manner is essential for organizing and making accessible the growing number of rich resources available on the Web. The success of digital libraries, the sustenance of interoperability – as promoted by the Open Archives Initiative – and the evolution of Semantic Web all rely on efficient metadata generation. This article sketches a metadata generation framework that involves processes, people and tools. It also presents selected research initiatives and highlights the goals of the Metadata Generation Research Project. http://tc.eserver.org/22392.html http://tc.eserver.org/22392.html Metadata has taken on a new look with the advent of XML and digital resources. XML provides a new versatile structure for tagging and packaging metadata as the rapid proliferation of digital resources demands both rapidly produced descriptive data and the encoding of more types of metadata. Two emerging standards are attempting to harness these developments for library needs. The first is the Metadata Object and Description Schema (MODS), a MARC-compatible XML schema for encoding descriptive data. The second standard is the Metadata Encoding and Transmission Standard (METS), a highly flexible XML schema for packaging the descriptive metadata and various other important types of metadata needed to assure the use and preservation of digital resources. http://tc.eserver.org/22152.html http://tc.eserver.org/22152.html The information model is a framework for organizing all the information people need. http://tc.eserver.org/21626.html http://tc.eserver.org/21626.html XML syntax is just the foundation for data interoperability. The next step is semantic transparency. Some groups are working to address this by defining entire document formats to be adopted wholesale, while other groups are working on ways to express common terminology and concepts at a more granular level. In this installment, Uche Ogbuji looks at XML Topic Maps Published Subjects and Universal Data Element Framework (UDEF), two ideas that take the granular approach by seeking to provide anchors in the semantic stream. http://tc.eserver.org/21599.html http://tc.eserver.org/21599.html This is a general collection of my Semantic Web hackings, often using CWM and the Notation3 (N3) format. http://tc.eserver.org/21598.html http://tc.eserver.org/21598.html It is important that on the Semantic Web, people produce data that is clean and interoperable. Some RDF techniques can currently only be learned through the RDF community, through hours of research, or through implementation experience, so this is an attempt to gather some useful but quick hints and tips into one place. http://tc.eserver.org/21597.html http://tc.eserver.org/21597.html The Semantic Web is a conceptual information space in which the resources identified by URIs can be processed by machines. It operates on the principles of 'partial understanding' and 'inference' (being able to infer new knowledge of terms from data that you already understand), and hence evolution and transformation. Because the URIs are being used to represent the resources, systems can grow on a globally decentralized basis, similar to hypertext documentation systems on the early WWW. http://tc.eserver.org/21603.html http://tc.eserver.org/21603.html Hace casi tres años comentábamos que la promesa de la web semántica era convertir la red en 'un espacio auto-navegable y auto-comprensible.' ¿Dónde estamos hoy en día?. http://tc.eserver.org/21499.html http://tc.eserver.org/21499.html In the domain of aerospace/defense, a products life cycle may likely span up to 30 years. The amount of technical data required to manufacture, operate, and maintain those products is immense. The graphic representation of that data facilitates the communication of operational and maintenance instructions. This paper outlines issues with creating, authoring, revising, and delivering intelligence with graphics and the associated meta-data. http://tc.eserver.org/21286.html http://tc.eserver.org/21286.html Recently Boxes and Arrows caught up with Samantha Bailey, formerly at Argus and current lead IA for Wachovia Corporation's Wachovia.com website. She talks about the transition from being a consultant to an 'innie' IA, unravels the mysteries of metadata and taxonomies and shares her vision of the future of IA. http://tc.eserver.org/21278.html http://tc.eserver.org/21278.html The online world has been flooded in recent years with talk of metadata, structured authoring, and cascading style sheets. The idea of a semantic web is gaining momentum. At the confluence of these two broad categories of activity, new models of websites are emerging. http://tc.eserver.org/21249.html http://tc.eserver.org/21249.html What is Dublin Core? And why would you need a whole conference about it? The end of September and beginning of October brought representatives from various countries around the world to a sunny and warm Seattle, Washington, host of the 2003 Dublin Core Conference. http://tc.eserver.org/21184.html http://tc.eserver.org/21184.html Discusses some different ways of describing your document structure so that both computers and humans know what you mean. http://tc.eserver.org/21003.html http://tc.eserver.org/21003.html This document is not intended to teach you RDF via my own words, but rather to hand-hold you through the 'good' parts of the same journey I took. If it looks like a big link-list with menial comments from the peanut gallery, then you're not far off the mark of my intent. This is by no means definitive, nor was that the goal. http://tc.eserver.org/21002.html http://tc.eserver.org/21002.html This document is designed as being a simple but comprehensive introductory publication for anybody trying to get into the Semantic Web: from beginners through to long time hackers. Recommended pre-reading: the Semantic Web in Breadth. http://tc.eserver.org/21001.html http://tc.eserver.org/21001.html This piece speaks about the different parts of the Semantic Web and how they fit together. http://tc.eserver.org/20944.html http://tc.eserver.org/20944.html With the adoption of eXtensible Markup Language (XML) on the rise, researchers in academia and industry are seeking to leverage the descriptive power of metadata to better understand the semantic structure of information (e.g., see Berners-Lee, 1998). But most interaction on the World Wide Web is what Geisler (2001) calls “document-centered,” involving the exchange of discourse a great deal larger and more complex than the basic units of meaning that semantics deals effectively with. As a result, the tools of semantics fall short of providing adequate metadata schemes which capture the most compelling features of effective discourse in any medium: emotional and ethical appeals which work in conjunction with appropriate logical and semantic structures. http://tc.eserver.org/20897.html http://tc.eserver.org/20897.html 'There is a singular lack of vocabulary control in the field of controlled vocabularies,' Bella Hass Weinberg, professor of library science at St. John's University in New York, is fond of saying. To help you cut through the maze of verbiage often found in this field, we have created a glossary of terms. http://tc.eserver.org/20813.html http://tc.eserver.org/20813.html This service will retrieve a Web page and automatically generate Dublin Core metadata, either as HTML META tags or as RDF/XML, suitable for embedding in the HEAD section of the page. http://tc.eserver.org/20812.html http://tc.eserver.org/20812.html The Dublin Core Metadata Initiative is an open forum engaged in the development of interoperable online metadata standards that support a broad range of purposes and business models. DCMI's activities include consensus-driven working groups, global workshops, conferences, standards liaison, and educational efforts to promote widespread acceptance of metadata standards and practices. http://tc.eserver.org/20736.html http://tc.eserver.org/20736.html The 2002 Dublin Core annual conference and workshop marked the beginning of a new effort by the Dublin Core Metadata Initiative (DCMI) to involve members of the corporate world in the evolution and application of the Dublin Core standard. The first meetings of two DCMI Circles of Interest were held on Monday, October 14, 2002, followed the next day by a panel session with several members of the Circles presenting their initial observations and conclusions to the wider conference. http://tc.eserver.org/20390.html http://tc.eserver.org/20390.html Proposes the design of an XML-based type library format. If you've had exposure to Microsoft COM or Mozilla's XPCOM, you're probably familiar with their binary TLB (MS) and XDT (Mozilla) formats that define the available operations and interfaces for a package of portable components. An interpreted language such as JavaScript can use these definitions as cheat sheets to find out what operations and parameters are available to call on-the-fly. http://tc.eserver.org/19679.html http://tc.eserver.org/19679.html Discusses some different ways of describing your document structure so that both computers and humans know what you mean. http://tc.eserver.org/19536.html http://tc.eserver.org/19536.html This is the story of how one commercial metadata standard — XBRL, or Extensible Business Reporting Language — has attracted the participation and support of some of the world’s most powerful public and private organizations. It begins with a look at the nature and use of financial information in today's Internet-enabled environment and discusses three information use patterns: Transaction, retrieval, and reporting. While numerous, sometimes competing standards have been developed for transaction information, XBRL alone has emerged to address reporting formats. Today, the XBRL specification has wide support across the accounting, financial, and regulatory communities. This has come about largely through the efforts of the standards’ governing board, which has pursued a strategy of careful definition of market scope, deliberate courtship of important allies, and establishment of a culture of aggressive outreach for members. The results are impressive. Members of the organization are now positioned to take greatest advantage of a number of new entrepreneurial opportunities that have been created by the organization. Additionally, some participants are now representing the XBRL metadata standard as a key tool for the restoration of public confidence in the scandal-rocked accounting and investment industries. This may create a serious problem for researchers and investors as unaudited financial statements formatted in XBRL proliferate on the Web sites of corporations anxious to demonstrate a commitment to what some are calling 'the new transparency.' http://tc.eserver.org/19259.html http://tc.eserver.org/19259.html Keywords and keyphrases have many useful roles as document surrogates and descriptors, but the manual production of keyphrase metadata for large digital library collections is at best expensive and time-consuming, and at worst logistically impossible. Algorithms for keyphrase extraction like Kea and Extractor produce a set of phrases that are associated with a document. Though these sets are often utilized as a group, keyphrase extraction is usually evaluated by measuring the quality of individual keyphrases. This paper reports an assessment that asks human assessors to rate entire sets of keyphrases produced by Kea, Extractor and document authors. The results provide further evidence that human assessors rate all three sources highly (with some caveats), but show that the relationship between the quality of the phrases in a set and the set as a whole is not always simple. Choosing the best individual phrases will not necessarily produce the best set; combinations of lesser phrases may result in better overall quality. http://tc.eserver.org/19256.html http://tc.eserver.org/19256.html In this paper, we argue that a core ontology is one of the key building blocks necessary to enable the scalable assimilation of information from diverse sources. A complete and extensible ontology that expresses the basic concepts that are common across a variety of domains and can provide the basis for specialization into domain-specific concepts and vocabularies, is essential for well-defined mappings between domain-specific knowledge representations (i.e. metadata vocabularies) and the subsequent building of a variety of services such as cross-domain searching, browsing, data mining and knowledge extraction. This paper describes the results of a series of three workshops held in 2001 and 2002 which brought together representatives from the cultural heritage and digital library communities with the goal of harmonizing their knowledge perspectives and producing a core ontology. The knowledge perspectives of these two communities were represented by the CIDOC/CRM, an ontology for information exchange in the cultural heritage and museum community, and the ABC ontology, a model for the exchange and integration of digital library information. This paper describes the mediation process between these two different knowledge biases and the results of this mediation - the harmonization of the ABC and CIDOC/CRM ontologies, which we believe may provide a useful basis for information integration in the wider scope of the involved communities. http://tc.eserver.org/18985.html http://tc.eserver.org/18985.html Information models are a critical component of single-sourcing, enterprise content management, and dynamic content management. This session explains how to design information models, including information product models and element models. It also explains the role of metadata and how to effectively design it. http://tc.eserver.org/18734.html http://tc.eserver.org/18734.html Los metadatos son información relativa a otra información. Al definir un grupo de metadatos para un objeto dado, estamos describiendo el objeto en cuestión, lo estamos caracterizando. Por ejemplo, HTML permite definir metadatos para una página web a través de su etiqueta <meta>. Esos metadatos (author, keywords...) caracterizan la página, describen su contenido. Los metadatos, utilizados tradicionalmente en el entorno bibliotecario, están resultando de gran utilidad en la Web, tanto en Sistemas de Recuperación de Información (back-end) como en Sistemas de Navegación (front-end). http://tc.eserver.org/18717.html http://tc.eserver.org/18717.html The Dublin Core Metadata Initiative (DCMI) is an organization dedicated to promoting the widespread adoption of interoperable metadata standards and developing specialized metadata vocabularies for describing resources that enable more intelligent information discovery systems. http://tc.eserver.org/18718.html http://tc.eserver.org/18718.html XFML (eXchangeable Faceted Metadata Language), creado por Peter Van Dijck, es un lenguaje o vocabulario con sintaxis XML para definir, distribuir e intercambiar metadatos en forma de taxonomías o clasificaciones facetadas. http://tc.eserver.org/18719.html http://tc.eserver.org/18719.html Since BBCi launched in November 2001, its search offering has been collecting data on the way that BBC website users search both the BBC's website, and through its homepage Websearch , the whole wide web. Given such a mass of data, the easiest way to aggregate and make sense of it has been to measure the search terms that are most popular. Indeed, the BBCi homepage has a panel displaying the three most popular search terms of the moment, and an editorial and taxonomy team at the BBC constantly monitor the searches gaining high volume in order to match the correct content to them. http://tc.eserver.org/18723.html http://tc.eserver.org/18723.html FacetMap is both a data model and a software package, created to let users browse complex metadata while retaining a simple, familiar, menu interface. http://tc.eserver.org/18712.html http://tc.eserver.org/18712.html Topic maps are a standard for storing metadata (similar to thesauri, or RDF). They can be used to generate navigation for a website, and lots of other metadata tasks. Topic maps are a new standard (since + 2000) and are slowly starting to be discovered. http://tc.eserver.org/18713.html http://tc.eserver.org/18713.html XFML Core is an open XML format for publishing and sharing hierarchical faceted metadata and indexing efforts. XFML Core is lightweight and easy to implement, yet uniquely powerful. http://tc.eserver.org/18309.html http://tc.eserver.org/18309.html This article provides an overview of work completed at Tsinghua University Library in which a metadata framework was developed to aid in the preservation of digital resources. The metadata framework is used for the creation of metadata to describe resources, and includes an encoding standard used to store metadata and resource structures in information systems. The author points out that the Tsinghua University Library metadata framework provides a successful digital preservation solution that may be an appropriate solution for other organizations as well.
