22. Status
• Publicly Available iserve.kmi.open.ac.uk
• Support for WSMO-Lite, MicroWSMO,
SAWSDL, OWL-S
• Around 2000 services
• OWL-S and SAWSDL Test Cases
• Import from Seekda
• Real services
• Already taken up by others (e.g., Notube)

23. Future Work
• Full import of Seekda’s data &
automated enrichment
• Addition of social features (e.g.,
reviews, comments, etc)
• Higher-level discovery API

24. Reflections on
Open Repositories
• Take care of all the storage and
publication needs transparently
• Linked Data principles for publication
• Shared simple and versatile
model(possibly involving
transformation)
• Public (RESTful) API
