Go shopping at the Park’s largest shop located just beyond the main entrance... Everything you may need for a park visit can be found at the Mini Market which stocks handy and personal items to keep you refreshed and ready for more adventures in the park... Colours, creativity and cool stuff are available at The Brick Shop where a wide array of LEGO® accessories... From freshly baked breads to savoury treats to sweet desserts, the Café satisfies every craving at the Park...Stuart Weibel and Eric Miller The Web is an important universal information tool, embracing vast stores of information with many purposes, multiple disparate sources, and quite a few unpredictable users. is a clear need to improve access to this mass of information and for the development better search, retrieval, and organizational tools. Metadata (data about data) is a fundamental part of the solution to these challenges. Effective use of metadata requires three things: a set of commonly-understood terms
describe the content of information resources (semantics); a standard grammar for those terms in meaningful metadata sentences; and a framework that allows us to exchange recombine those metadata sentences across different applications and subjects. elements -- standardized semantics, a definitive syntax, and a framework for exchange provide an architecture for resource description that can work across all subject Developing a single and complete vocabulary for resource description is a difficultTackling this effort in a flexible fashion, however, allows for an incremental solution with manageable constituent parts. Lego, the familiar building blocks of is the perfect metaphor for describing how metadata can be incorporated into the Web support the management of information. Lego blocks come in themes, consisting of simple colored bricks created with consistent, engineered dimensions that allow them to snap together with a satisfying click.
The Dublin Core Metadata Element Set (DCMES) can be viewed as the common semantic building block of WebIts 15 broad categories (elements) are useful for creating simple, easy-to-understand descriptions for most information resources. additional semantics to fully describe their resources, however. So, just as simple blocks can be combined to form complex structures, various modules of metadata can combined to form more complex descriptions. The DCMES is the basic block, but other of metadata can be combined with it to form richer descriptions. The basic element set is intended to capture most of the fundamental descriptive categories necessary to promote effective search and retrieval. Additional building blocks can created to provide modular chunks of metadata that can be built into richer descriptionsSo, just as Lego blocks of various shapes can be snapped together form undersea exploration themes, or recombined to create spaceships or medieval castles,
chunks of metadata can be combined and recombined to meet the functional requirements The Dublin Core Metadata Initiative provides a forum for the definition of semantics, for a general description core and for subject-specific extensions. vocabularies be integrated into a functional architecture? Dublin Core metadata can carried in HTML, XML, and RDF. The latter, the Resource Description Framework, builds on the World Wide Web Consortium's (W3C) effort to design an architecture for metadata on the Web. supports many different metadata needs of vendors and information providers. Metadata Element Set can be thought of as a Lego that is common to many sets, RDF engineering standard that enables that satisfying click when the blocks are snapped RDF is part of an infrastructure that will support the combination of Dublin Core into larger, more expressive metadata structures that will work with one another. applications should be able to mix metadata from other semantic standards expressed
Just as different Lego sets express undersea, outer space or medieval castle themes, RDF can enable snapping together modules that support metadata themes for government, or commercial purposes, all working together in the same architecture. example, members of the RSS community have recently been advocating RDF as a powerful, modular means of combining semantics defined by Dublin Core with additional vocabularies (syndication, aggregation, threading) produce effective site summaries and syndication services. an example of how this used as a modular means for combining semantics is the following. The mission of the Dublin Core Metadata Initiative (DCMI) is to make it easier to resources using the Internet through the following activities: The Dublin Core metadata element set (or the basic Lego brick) is intended to support cross-subject search and retrieval. It can be thought of as a simplistic or pidgin language that helps the user navigate through disparate subjects, languages, and cultures.
Adoption of the Dublin Core by governments, libraries, museums, archives, publishers, environmental science repositories, print and e-print archives, to name a few, testifies its success in this role. There are emerging applications in the commercial sector, with health care organizations and financial industries using the Dublin Core as the for organizing and exchanging information. Part of the mission of DCMI is to provide a vendor-neutral forum for the development additional vocabularies that are interoperable within the broader architecture of Core and other Web metadata schemas in general. At the recent 8th Dublin Core metadata workshop in Ottawa, Canada, a special interest group formed around the exploration of metadata issues that are of particular interest to the business community. for this group is to provide a forum: Interested parties may subscribe to the discussion list. In addition to providing international forums for the development of vendor-neutral
vocabularies, the DCMI is promoting the development of tools and infrastructure to high quality metadata applications on the Internet, including The registry activity is a fundamental part of both the management and use of metadata, allowing, in the short term, the registration and public disclosure of metadata schemas granularity that allows management and discovery of descriptors at the element level. Metadata schema developers will use the registry to discover what other applicationsUsers will be able to identify the precise definitions of elements, and applications will be able to resolve machine-processable mappings among different further enhancing the prospects for Web-wide metadata interoperability. By supporting the development of such tools in an open source environment, the DCMI to promote broad contribution of value by the community at large. While the Dublin Core began with the goal of developing a simple, interoperable,
