Currently, there are several instances of the catalogue running, including:
- BioCatalogue – a catalogue of life science Web services
- BiodiversityCatalogue – a catalogue of biodiversity Web services
- PANACEA catalogue – a catalogue of Web services that automate the process of acquisition, production, maintenance and updating of the language resources required by machine translation
Note that these are live sites used by scientists and researchers.
There is also a test site, test.biocatalogue.org, which you can use to play with the catalogue and familiarize with its features.
