Because the definition of the terms often contains domains and ranges, which may not be compatible with the pre-RDF definitions used for the original 15 Dublin Core elements, there is a separate namespace for the original 15 elements as previously defined: Retrieved from ” https: International Digital Publishing Forum.
The Dublin Core Schema is a small set of vocabulary terms that can be used to describe digital resources video, images, web pages, etc. The DCMI has established standard ways to refine elements and encourage the use of encoding and vocabulary schemes. If an encoding scheme is not understood by an application, the value may still be useful to a human reader.
Because ISO is so popular, it is probably useful for providing high-level metadata of the likes of a dataset series e. Such a reference model allows implementers to gain a better understanding of the kinds of descriptions they are trying to encode and facilitates the development of better mappings and translations between different syntax.
It is widely used for describing ido and other resources, not only within the library community where it originated. There is 15863 prescribed order in Dublin Core for presenting or using the elements.
However, because it uses free text and is at a high level, it is difficult to use effectively any such metadata describing an individual geographic dataset, never mind describing individual features within the dataset.
Simple Dublin Core comprised 15 elements; Qualified Dublin Core included three additional elements Audience, Provenance and RightsHolderas well as a group of element refinements also called qualifiers that could refine the semantics of the elements in ways that may be useful in resource 18536.
Archived from the original on 16 November PBCore is also based on Dublin Core. Each Dublin Core element is optional and may be repeated.

A refined element shares the meaning of the unqualified element, but with a more restricted scope. When considering an appropriate syntax, it is important to note that Dublin Core concepts and semantics are designed to be syntax independent and are equally applicable in a variety of contexts, as long as the metadata is in a form suitable for interpretation both by machines and by human beings. These schemes include controlled vocabularies and formal notations or parsing rules. A value expressed using an encoding scheme may thus be a token selected from a controlled vocabulary for example, a term from a classification system or set of subject headings or a string formatted in accordance with a formal notation, for example, “” as the ISO standard expression of a date.
In addition to element refinements, Qualified Dublin Core includes a set of recommended encoding schemes, designed to aid in the interpretation of an element value. As part of an extended set of DCMI metadata terms, Dublin Core became one of the most popular vocabularies for use with RDF, more recently in the context of the linked data movement.

While this may result in some isp of specificity, the remaining element value without the qualifier should continue to be generally correct and useful for discovery.

Retrieved 3 April Syntax choices for Dublin Core metadata depends on a number of variables, and “one size fits all” prescriptions rarely apply.
The Dublin Core Metadata Initiative DCMI  provides an open forum for the development of interoperable online metadata standards for a broad range ios purposes and of business models.

The Dublin Core standard originally included two levels: Starting inthe Dublin Core community focused on ” application profiles ” — ios idea that metadata records would use Dublin Core together with other iao vocabularies to meet particular implementation requirements. Views Read Edit View history.

Dublin Core metadata may be used for multiple purposes, from simple resource description to combining metadata vocabularies of different metadata standardsto providing interoperability for metadata vocabularies in the linked data cloud and Semantic Web implementations.
