A metadata aggregator is an entity which collects, proofs and publishes metadata from an alternate location than one associated with any individual collection. The scoping study aimed to:

  • Explore what it means to have aggregations of metadata about images and time-based media (films and sounds), through a number of questions, which included:
    • What collections should be considered?
    • What are the metadata considerations?
    • What, or who would such a metadata aggregation serve?
    • How can the metadata be gathered and shared?
    • What are the issues that must be resolved?
  • Provide insight into the benefits of, and opportunities for, such aggregations.
  • Better understand the challenges and barriers to making collections of open metadata available.
  • Describe some scenarios in which aggregations of open metadata about images and time-based media could be useful or required.

  • Whether and where normalisation and enrichment of metadata takes place.
  • Working with commonly used web interfaces (e.g. RESTful APIs, RSS[i] and ATOM[ii], which may be used to access the aggregation) and those standards used within the academic, museum, and archive sectors (e.g. OAI-PMH and SRU (Search/Retrieval via URL), which enable metadata harvesting and access).
  • The focus being the aggregation of metadata rather than a user interface(s) onto the aggregation (for a particular use case such as search).
  • Whether aggregations could be exploited more effectively by being made available in linked data format.
