There is an important use case missing from the list which probably fits closest within this section, or possibly in 1.1. One of the biggest issues we face is demonstrating the role and value of collections. This is often a national challenge because this is where the funding lies, but on occasion becomes a continental or global challenge. A collections catalogue is the foundation for this form of advocacy, demonstrating the power, relevance and diversity of usecases. The data can be used to build funding cases, show current (often national) capacity), and highlight gaps. Related to this, there is significant potential use these data as a management tool at a range of spatial scales to demonstrate strengths, weaknesses and capacity of collections. Again, this level of management is often local (national) but requires global coordination and needs founding on the catalogue data as the first line of evidence.
