At the December 2002 CENDI meeting, Ms. Funke and Mr. Tracy updated the CENDI members on research and products under development at EPA. The Environmental Information Management System (EIMS) status update was presented by John Sykes of the Office of Research and Development (ORD). This system now has over 31,000 records and will soon be adding the Science Inventory which is all research in the agency. Also financial information is being integrated with products to provide better accountability of what a project costs. Following this update, another status report was given on "Window to My Environment", a public access portal that addresses practical problems of GIS data integration and deployment. Because there is no agreement on the Open GIS Standard, XML is being used to integrate EPA information with partner information. The last update described the Environmental Data Resistry (EDR) which supports EPA's efforts in data standardization by cumulating definitions of data elements from a variety of EPA databases, products, and projects. It utilizes the ISO 11179 standard and provides a single source for their definition. Currently there are over 7,000 data elements defined in the EDR. A chemical data registry has also been developed with approximately 80,000 chemicals.
At the April 2002 CENDI meeting, Ms. Davids provided a brief overview of the metadata template being used at NAL. It is used for documents created by NAL staff and for materials that are digitized from print for preservation purposes. Elements of the template include preservation, content stability, and support access. NAL is using Handles in the prototype system. XML will be included in the final system.
At the February 2002 CENDI meeting, Ms. McCray provided an overview of Profiles in Science, a web site that captures the papers, photos, and related memorabilia of Nobel Laureates. The project has seven collections to date. Work on the project began in the early 1990's and has involved converting paper to digital form. The project developed its own metadata and has clear semantics for their data elements that allow other metadata schemes to be used as needed for importing or exporting information.
At the CENDI meeting on April 15, 2003 at USGS, Ms. Roy explained the National Biological Information Infrastructure's (NBII) vision of geospatial access is that all resources, information, and data within the NBII Web, when spatially relevant, will be referenced and retrievable in an interoperable manner. There are three major components in NBII's project: geographically referenced web pages; map viewing capability; and a centralized map service registry. The registry is to be completed by early summer and NBII nodes will be required to comply within six months.
The Guide presents an overview of metadata practices in publishing and related initiatives aimed at standardizing how metadata is structured and disseminated online. Metadata in publishing can be classified according to specific functions, such as technical metadata, rights metadata, and preservation metadata. The authors focus on descriptive metadata that characterizes the content itself. The Guide covers metadata's relationship to XML and to identifiers, why metadata is important to publishers and the reader, and then covers several metadata practices in the publishing industry including ONIX, JWP, CrossRef, and OAI. The authors conclude that metadata is an essential part of the publishing process and provides an extensive list of information resources on electronic publishing.
Metadata initiatives for six CENDI agencies are described. The emphasis is on metadata for non-traditional projects such as multimedia, curriculum and educational materials, and web site cataloging. Issues and concerns are identified along with recommendations for CENDI follow-up.
In the context of the need to keep up with the content on the Internet that would be of value for the Scout Report's Signpost catalog of Internet resources, the article describes an approach to linking distributed collections of metadata so that they can be searched as a single collection. The infrastructure, based on the Lightweight Directory Access Protocol (LDAP) and the Common Indexing Protocol (CIP) is described. The advantages of using linked metadata as opposed to keyword indexing searching are discussed. Other architectures for metadata discovery are also outlined. Research issues and future directions for the project are included. The Internet Scout Project was funded by NSF.
A metadata format used by federal agencies, including science agencies, to identify government resources at various levels. Required by OMB Circular A-130 (Paperwork Reduction Act) and FIPS 192. GILS is also used internationally.
A metadata format for geospatial data required within the federal government by Executive Order when the original information can be referenced geospatially (i.e., by latitude and longtitude coordinates).
The OMB Bulletin that establishes the requirement within government agencies to identify resources of value to the public using the Government Information Locator Service (GILS) metadata standard.
This site describes the history of the Dublin Core metadata element project, gives definitions and technical details about the scheme, points to sites and projects that are using the Dublin Core scheme, and identifies outstanding issues being addressed by the working groups.
The final report of a study commissions by the GILS Board in 1995. It includes the findings of research into the current status, use and user satisfaction with the Federal GILS implementation, and make recommendations for improvements.
Draft of the specifications for the Resource Description Framework (RDF) which will allow multiple metadata formats to interoperate. It will also allow nesting of metadata to show parent child relationships. This is a working draft and subject to change at any time.
An international association of national library associations and other related information centers. Provides organization information, calendar and links to sites of interest to the constituency including a site that provides links and a bibliography on metadata.
Outlines responsibilities of government agencies to implement GILS and provide progress reporting and feedback mechanisms.
This working paper suggests a standard set of genre types to be used in the Dublin Core metadata element "resource type".
This site introduces the IMS project for managing online learning resources (people, educational service companies, content, tools and activities) under development by EduCom and the NLII initiative and gives an overview of the concept of meta-data. A detailed description of the IMS metadata specification is presented in the IMS Meta-data Dictionary which describes each field according to the ISO Standard 11179. Fields correlating to Dublin Core are "starred". The Meta-data Tool software, Forum, and Meta-data Listserv are linked to the site. The IMS project represents a major initiative for managing learning resources on the Web by the academic and other communities. The crosswalk to Dublin Core indicates potential for Web-based resource sharing among communities who adhere to common standards.
The workshop focused on the characteristics and features of images, image production and reformatting features, and image identification and integrity issues in relation to preservation and archiving. The group agreed on a preliminary list of technical metadata elements specifically required for images, and follow-up efforts needed to future standardize
The Metadiversity Symposium held at Natural Bridge, VA on November 9-12, 1998 was sponsored by the National Federation of Abstracting and Information Services and the Biological Resources Division of the US Geological Survey as a means of identifying research directions in the area of metadata for biodiversity and ecosystem sciences. This is part of the National Biological Information Infrastructure. This site provides links to preprints of the symposium papers, notes from the symposium, and the preliminary program. The final report is available from NFAIS in hard copy.
This is the final report from the Task Force that was established with five charges: analyze the resource description needs of libraries, build a conceptual map of the resource description landscape and develop models for accessing and using metadata, devise a definition of metadata and investigate the interoperability of emerging schemes with current MARC rules, recommend ways that libraries could best incorporate metadata schemes into current library practices, and recommend rules revisions to AACR2. The charges are addressed in this summary document. It also contains links to prototype systems, a glossary of terms, and concludes by handing over its results to the ALCTS standing Committee on Networked Resources and Metadata.
The creation of the FGDC through Circular A-16 (1990) was described. Almost every executive agency produces geographic data of some sort. The FGDC's outreach activities, technology, policies, and standards are discussed. The current status and standards activities related to the FGDC Metadata Content standard was outlined. The FGDC's activities with cooperating universities and the National Spatial Data Infrastructure is also described.
Dr. Kahin is involved in areas of competition and private sector/government interaction. Under these board issues, he is addressing issues of domain names and network numbers, metadata (labeling) for Internet sites, and copyright and intellectual property (database protection and digital copyright). These areas of interest are briefly discussed.
This white papers presents the key issues involved in the development of crosswalks between different metadata standards. It promotes the idea of harmonization when developing standards, so that families of standards are created that are more easily crosswalked. The paper calls for the development of a Metadata Specification Language (MSL) that would provide a consistent format and language for the documentation of a metadata standard.
This article describes an analysis of 466 Federal Geographic Data Committee (FGDC) metadata records stored in the National Biological Information Infrastructure (NBII) section of the FGDC's Clearinghouse, and reviews issues regarding conversion of these records into MARC21 and Dublin Core. Special attention is paid to the length of fields as well as length of all the records analyzed.
Home page for the Cedars Project. The Project is a Higher Education initiative funded by the Joint Information Systems Committee through the eLib program. Cedars stands for CURL (Consortium of University Libraries) exemplars in digital archives.
Newest version of specifications of the Resource Description Framework (RDF) which allow multiple metadata formats to inter-operate. It will also allow nesting of metadata to show parent child relationships. This version is the recommendation of W3C.
This report recaps some of the important milestones for 2000 including the standardization of the 15-element core foundation and approval of an initial array of Dublin Core Qualifiers. It also describes the new mission statement of the Dublin Core Metadata Initiative (DCMI) and summarizes the 2001 workplan.
This article explains the concept of "Dublin Core" as a metadata language for the Web. The author defines it as a small language for making a particular class of statement about resources. Dublin Core has a vocabulary of word-like terms which are composed of elements and qualifiers. The elements and qualifiers function within statements like nouns and adjectives. There is also a syntax for arranging elements and qualifiers into statements. The author's use of the sentence and its parts is effective in describing the essence of Dublin Core.
This book written by three experts who are involved in the development and implementation of information standards, presents an indepth discussion of metadata, detailing types, functions, attributes, and characteristics with examples. The book is divided into three sections, the first of which sets the stage by defining metadata and its many faces, and concluding by posing several key questions that must be resolved by information professionals as they develop digital systems. The second section discusses metadata and standards in the context of the World Wide Web, and outlines issues, opportunities, and challenges. The third section covers the mapping of different metadata standards to facilitate interoperability.
This Conference Web site provides access to the papers and discussions presented at the November conference held at the Library of Congress. The goal of this conference was to develop an overall strategy to address the challenges of improved access to Web resources through library catalogs and applications of metadata. Another goal was to identify actions that would achieve the objectives of the overall strategy. One of the main topics at the conference was a discussion of current library standards for bibliographic control and web access. The recommendations and fulltext papers from the conference are available at this site.
Minutes from a presentation by Clyde Housel, Systems Design Engineer, National Imagery and Mapping Agency (NIMA) at the CENDI meeting on April 6, 1999. Mr. Housel provided a brief overview of NIMA and indicating that it has approximately 260 organizations and 6,000 users who access their imagery indirectly. NIMA is in the process of developing th United States Imagery and Geospatial Information System (USIGS) Architecture. This encompasses the structure of components, their relationships, and the principles and guidelines governing their design and evolution over time. The Architecture will provide through interoperable systems and metadata, access to imagery and mapping information across the partner organizations and will integrate these remote sources seamlessly with the customer's own libraries. The design of the architecture is separated into Operational Architecture, Systems Architecture, Technical Architecture and Conceptual Data Model which ties all the components together. The new system will allow for more customization of data and more precise information on a smaller topographic area.
The Universal Description Discovery and Integration (UDDI) standard registry is an initiative that creates a platform-independent, open framework for describing services, finding businesses, and integrating business services using the Internet. The UDDI standard was driven by platform and software providers, marketplace operators, and e-business leaders. The Web site explains the benefits of using the UDDI standard including the ability to reach new customers, extending market research, increasing access to customers, etc. The Web site prompts businesses to register their services. Also included on the UDDI homepage are press releases and news articles, as well as white papers that provide a more indepth explanation of UDDI and its specifications and structure.

Occassionally special issues are published that focus on a specific topic such as networked knowledge organization systems in volume 1, issue 8, April 2001 issue. At the current time the journal is free, however, as the site becomes more developed, a fee will be charged. Jodi also offers a free alert service for notification of new issues of the journal.
This paper describes Cornell University Library's project to develop and implement a digital preservation strategy for their collection of over two and a half million mission images. Over a two year time period, the project inventoried thirty different digital image collections, investigated emerging file formats for long-term utility, explored functional requirements for storage, and drafted recommendations for the preservation of metadata. A working group was established to present the recommendations to the Library Management Team. The Project's final report will cover conversion and metadata requirements, strategies for storage, maintenance and long-term care, and an assessment of resource needs.
