WS-VLAM Introduction presentation WS-VLAM Semantic tools Systems, Networking, and Engineering group Institute of informatics University of Amsterdam

WS-VLAM Introduction presentation Introduction This presentation contains information related to Semantic tools developed to support WS-VLAM It helps the reader understand the main features of each tools. NOTE:  We are currently still working on the User ’ s and developer ’ s Guide, they are not available at this time. The presentations do not replace the documentation it just give a quick introduction.  Do not hesitate to contact us for further information Thanks for taking some of your time to read about the WS-VLAM work, any comments are more than welcome WS-VLAM developers

WS-VLAM Introduction presentation Needed background … To be able to follow the content of this presentation you will need to know about:  OWLS= OWL-S: Semantic Markup for Web Services. OWLS More detailed description of the presented work can be found in the section of documentation of the WS-VLAM home pageWS-VLAM

WS-VLAM Introduction presentation Objective of this presentation … Why you should look at this presentations  You want to know how to use the semantic tools to created a the description of workflow component in WS-VLAM, annotate it, and perform a semantic search for WS- VLAM services. This presentation will not describe the following topics:  How to Compose a workflow: o See the WS-VLAM composer presentation or the User ’ s GuideWS-VLAM composer  How to create a workflow component o See the WS-VLAM developers presentation or Developer ’ s guideWS-VLAM developers

WS-VLAM Introduction presentation WS-VLAM e-Studio So far it is simple program, used to start the different tools developed in the VL-e project by the Virtual Laboratory and system integration groupVL-e

UvA, Amsterdam June 2007WS-VLAM Introduction presentation WS-VLAM e-Studio: Current available tools Clamp: Connecting Language for Module & Programs Composer: WS-VLAM workflow composer Saw: Semantic Annotation for Workflows Hammer: Hybrid-bAsed Match-Maker for e-Science Resource VBrowser: Virtual Browser

WS-VLAM Introduction presentation WS-VLAM Clamp Helps create workflow components description It is a Graphical interface, which allows the workflow component developers to define: –Input & Output ports –Parameters The output of this tools is an XML file which can be used as input for the workflow composer

WS-VLAM Introduction presentation WS-VLAM Saw Helps annotate workflow components based on OWL-S Ontology for services: Profile: tells what the service does Service Model: tells a client how to use the service OWL-S Graphic: The output of this tools is an OWL-S file which can be used as input for the Hammer for the Semantic discovery of services –OWL-S Source
