Thank you @Wenjun and @Maofang. We expect that “community catalogues” will be subsets of the “integrated catalogue” and that the data standards will normally be exactly the same.
A community catalogue could just be a section of the integrated catalogue that is maintained actively by, or on behalf, of all collections from a country or for a particular taxonomic group. In this case, the standards, and the data, will be exactly the same for both purposes.
Or a community catalogue could be more like Index Herbariorum, with its own database managed by the relevant community. In this case, there could be some differences in the standards used, but we would aim to map the data for discovery through the integrated catalogue.
I expect that we will be flexible between these two models.
