Metadata is defined as ‘information about information’. From a practical perspective it is used to facilitate the understanding, characteristics, and management usage of data. Metadata required for effective management of its referenced data varies with the type of data and context of use. For example, in a library, where the data can be considered as the content of the titles stocked, metadata about a title would typically include a description of the content, the author, the publication date and the physical location.
In the context of eLearning, metadata is especially useful as it has the potential to protect content – aka eLearning assets from a perspective of copyright.

In the context of Podcasting / new media / recorded social media interchanges, attributes associated with its use and ownership are both part of its metadata.

The following diagram shows an example of an eLearning content item and a range of information held about it, i.e: its metadata:

• Meta data standards are key when repurposing content -for example: Re-use - This borders on the concept of Shared Content Objects (SCOs), for example, a introductory video or audio that is redeployed at the start of every eLearning modules. Or, a corporate / learning podcast
• Naming conventions
• Storage location for content masters
• Subject cross-referencing
• Featured activities
• On-line location of other related eLearning - this is ideal for cross-curricula planning
• On-line location of other related podcasting subjects - ideal for cross-referencing other (inc: other people’s) broadcasts
• Version control
• Content owners - for example, intellectual property rights and re-use rights - imagine a recording of an exclusive interview
• Classification of content - similar to subject categories for library books
• Extent of interactivity expected from the content to be deployed inside an eLearning course or feedback to corporate communications.

If the correct metadata standards are in place with an agreed taxonomy, it is easier to map relevant content items (inc: both video and audio podcasts / new media) and eLearning courses, face-to-face sessions or effective corporate communication campaigns. The importance of record keeping and understanding what was previously released can also ensure:

• Good archiving disciplines
• Good cross-referencing
• Good strategies to avoid duplication
