Dublin Core enero 15, 2008Posted by Closto in Scholae scripta, Universitas.
Dublin Core is a metadata set working to provide the simple standard sets for describing online metadata. The aim is to make easier to find information, things or files. It is commonly used to describe things like audio, video, pictures, texts and even web pages.
The Dublin Core Metadata Element Set (DCMES) consists of 15 elements (Simple Dublin Core):
-Title: Title for the file. Tag: DC.Title.
-Creator: Name of the person, organisation or system that has created the file. Tag: DC.Creator.
-Subject: Key words or tags. Tag: DC.Sbject.
-Description: Summary of the file. Tag: DC.Description.
-Publisher: Name of the person, organisation or system that has published the file. Tag: DC.Publicher.
-Contributor: Name of the person, organisation or system that helps to create a file. Tag: DC.Contributor.
-Date: Date of an event happening during the timelife of the file. Tag: DC.Date.
-Type: Kind of the contents. Tag: DC.Type.
-Format: Phisic format type of the file (e.g., MIME). Tag: DC.Format.
-Identifier: Not an ambiguous idetifier. An accurate referring system is recommended (e.g., URI or ISBN). Tag: DC.Identifier.
-Source: Source fo the information for the files (formal notation systems such as URI are recommended). Tag: DC.Source.
-Language: Language of the file. Tag: DC.Language.
-Relation: Links to other resources. Tag: DC.Relation.
-Coverage: Time and place coverage. Tag: DC.Coverage.
-Rights: Copyright, intellectual property rights… Tag: DC.Rights.
There is a second level on the Dublin Core Metadata Element Set, the Qualified Dublin Core, which adds three new elements: Audience, Provenance and RightsHolder). Those are used to specify the wanted files and make the search more accurate.
The Dublin Core’s main advantages are the syntax simplicity, its easy use, the sintactic independece, the formal standarization, the DCMI growing power, the international approvement and its developed metadata structure.
Nine countries are involved in the cooperation for making the Dublin Core to be a success: Australia, Canada, Denmark, Finland, Ireland, Iceland, New Zeeland, the United Kingdom and The United States of America. Besides, the Dublin Coreholds up more than 15 DCMI groups working. Those are some teams among the 18 existing groups: DCMI Administrative Metadata Work Group, DCMI Architecture Work Group, DCMI Internationalization and Localization Interest Group, DCMI Standards Work Group, DCMI Tools Work Group, DCMI Global Corporate Circle IG, DC Agents Work Group, DCMI Education Work Group, DCMI Kernel/ERC (Electronic Resource Citation).
