Thanks @vsmithuk
There are some important aspects in this which are useful to validate the sketch for a collection catalogue design. In particular, you highlight the need to aggregate at spatial levels and highlight gaps; presumably requiring a comparison across collections or to some reference.
Can you please elaborate a little on this section?
A collections catalogue is the foundation for this form of advocacy, demonstrating the power, relevance and diversity of usecases.
Collating citations such as those found in taxonomic papers or tracking data downloads and the subsequent use are well-understood objectives. Have you ideas of other information feeds that can be accumulated or compiled?
