EdNA - Education Network Australia
|
In line with Australian whole-of-government initiatives and international metadata efforts the EdNA Reference Committee (now the Australian Information and Communication Technologies in Education Committee (AICTEC) has agreed that the EdNA Metadata Standard be based on the Dublin Core Metadata Element Set.
The Dublin Core Metadata Initiative (DCMI) is an international collaborative effort to establish and maintain standards for describing Internet resources with the aims of enabling targeted resource discovery and interoperability of information exchange.
Key principles of the Dublin Core metadata specification relevant to EdNA include:- Simplicity: The DCMES is intended to be usable by both resource description specialists as well as non-experts
- Interoperability: Promoting a commonly understood set of descriptors that enable the discovery of online information resources from across subject and interest domains
- Extensibility: The DCMES is intended as a core element set, or baseline, from which different communities can extend to meet their own specific needs – these can manifest as different levels of interoperability (local, domain-specific, national, global)
- Refinement: A set of recommended qualifiers (element refinements and encoding schemes) is available to refine the elements and identify standard schemes which define the content in various elements where more precision or control over content is required
- Dumbing-Down: The contents of DCMES descriptions will always make sense without the use of qualifiers so that elements are useful in applications which are not configured to handle the syntax of qualifiers being used in particular communities. The principle is known as the "dumb-down" principle

Guiding Principles
The EdNA Metadata Standard is based upon:- the primary objective of facilitating targeted resource discovery of online eduational resources
- a foundation grounded in international metadata standards initiatives, in particular the Dublin Core Metadata Initiative (DCMI) which interoperate with standards developed and promoted by the World Wide Web Consortium (W3C)
- remaining interoperable with the DCMI as it introduces refinements to its specification
- collaboration aimed at achieving and maintaining cross-sectoral consensus on a national education metadata framework and strategic directions for its evolution (recognising sector-specific requirements within the standard) - in other words, consensus between EdNA nominees from the school education, vocational education and training, and higher education sectors about an interoperable framework which also meets the needs of stakeholders locally
- positioning for interoperability with other national and international standards and schema (including intellectual property) - with a view to maintaining a balance between generality and specificity (including consideration of DCMI, AGLS and IMS schema)
- adopting and promoting the use of authoritative Australian classification schema wherever possible
- accommodating local values, such as state-specific learning outcomes information;
- providing guidance to stakeholders in recommended best practice
- pragmatic application (including consideration of all associated costs and overheads) with the primary goal of achieving baseline conformance to the standard

Metadata and EdNA Online
On EdNA Online, metadata is used to:- assist with user searches by allowing a more detailed specification of the type of material being sought (providing a more refined search than conventional search engines)
- weight search results so that words contained in metadata elements are given priority over words in the text of a document. (By default, the chance of finding relevant resources even if the user does not explicitly search on a metadata element are also increased.)
- automatically allocate items to categories in the EdNA Online browse directory;
- assist with management of EdNA Online content
- provide general cataloguing information which can enable documents in the EdNA Online database to be searched by other catalogues (for example to allow education documents entered in EdNA to be searched by libraries)
