iServe released

Dear all,
On the occasion of the Extended Semantic Web Conference that is about to 
start in Crete, we would like to announce publicly the release of iServe 
[1], a registry for publishing Semantic Web Services (SWS) as linked data.

In brief, iServe

  * is a registry of semantic Web service descriptions,
  * published as linked open data,
  * with a RESTful API and a SPARQL endpoint,
  * integrated with authoring tools,
  * supports multiple SWS formats,
  * contains existing real and test-suite service descriptions.

iServe is the first semantics-based Web service registry accessible
conveniently on the Web (see iServe Browser at [2]). The registry 
transforms service annotations expressed in a variety of formats into 
what we refer to as Linked Services -- linked data describing services 
-- that can directly be interpreted by state-of-the-art Semantic Web 
technologies for service discovery and further processing.

Currently, iServe supports SAWSDL, MicroWSMO, WSMO-Lite and OWL-S. It
provides an homogeneous view [3] that covers WSDL services as well as 
the increasingly popular Web APIs.

Service descriptions can be submitted to iServe using the iServe Browser 
user interface or directly via a RESTful API [4]. The data in the 
registry is publicly available following the principles of linked data 
(including a SPARQL endpoint at [5]). The data also links to the 
original descriptions so as to avoid any loss of information and retain 
the capabilities offered by the original descriptions.

iServe now contains service descriptions from these sources:

  * OWL-S and SAWSDL test collections [6,7],
  * descriptions of real services from the SOA4All project [8],
  * some service descriptions imported from Seekda [9].

iServe is well integrated with two browser-based annotation tools,
namely SWEET [10] & SOWER [11], which simplify the authoring and
publication of semantic annotations of services. SWEET supports users
in creating annotations of Web APIs, while SOWER deals with WSDLs.

iServe, SWEET & SOWER are all parts of a comprehensive tool suite, 
called SOA4All Studio which is under development as part of the EU 
project SOA4All [8]. The Studio includes support for service annotation, 
publication, consumption and analysis. Additional tools in the suite 
will be released in the forthcoming months.

- Alex Simov (SOWER)

Further thanks to Dave Lambert and members of the SOA4All project for 
their insightful comments.

A good part of the team will be present at ESWC so if you are there and 
want to discuss about iServe, feel free to approach us.
