Welcome to OPOSSum, a portal dedicated to work towards a common SWS test collection

What is all this about?

Despite significant research efforts in the field of semantic web services, real tools and applications using them are still rare. One of the main obstacles for improvements in this direction is the lack of sufficiently large and high-quality collections to test and evaluate tools and algorithms for semantic web services. Such collections cannot be built by any single group but only in a collaborative way by the community as a whole. The purpose of OPOSSum is to equip the community with the means to do so (more).

Please bring this project alive by adding your service descriptions!

What are OPOSSum's core concepts?

Basically, OPOSSum is a database of service descriptions. To be able to collect and compare different descriptions for the same service and to support the creation of collections across formalisms, OPOSSum is centered around the notion of a service, not of service descriptions (more).

What data is currently available and where does it come from?

The majority of services currently listed result either from the integration of existing SWS collections (OWLS-TC, SWS-TC, SAWSDL-TC) or an effort for building a service collecting based on real services from the geocoding domain. More information is available in the OPOSSum Data Guide.

How do I use OPOSSum?

You can access all data without an account, but you need to register in order to be able to add or edit data. Registration is fast and easy. OPOSSum is an academic project. We do not share your registration data with anybody.

How can I contribute?

OPOSSum is meant to be a tool by the community for the community. In this aspect community participation is not only needed to fill OPOSSum with data to bring it alive but also to provide the feedback to turn OPOSSum into a tool which fulfills the needs of the community. If you are missing a feature in OPOSSum please do not hesitate to contact us or consider to add it yourself. You may download the sources here.
