OGSI::Lite / WSRF::Lite
Contents
WSRF::Lite
WSRF::Lite follows on from OGSI::Lite (see below). It implements, in Perl, the Web Service Resource Framework (WSRF) which was inspired by and supersedes the Open Grid Services Infrastructure (OGSI). The OGSI specification is a proposed recommendation of the OGSI Working Group of the http://www.ggf.org/Global Grid Forum. Standardisation of WSRF is ongoing in the WSRF technical committee of OASIS. The University of Manchester contributed to the standardisation of WSRF as an OASIS member.
|
Development of WSRF::Lite is being supported by the Managed Programme of the Open Middleware Infrastructure Institute (OMII) through the project Robust Application Hosting under WSRF::Lite (RAHWL).
|
WSRF::Lite provides support for the following Web Service Specifications:
- WS-Addressing
WS-ResourceProperties
WS-ResourceLifetimes
WS-BaseFaults
WS-ServiceGroups
- WS-Security
WSRF::Lite from version 0.4 provides beta level support for signing and verifying SOAP messages using X509 digital certificates according to the OASIS standard for WS-Security. It has been tested with .NET and the Sun Web Service Developers Pack.
The latest version of WSRF::Lite is version 0.8.2.2, available at WSRF-Lite.0.8.2.2.tar. You can still download WSRF-Lite.0.8.2.1.tar, WSRF-Lite.0.8.tar, WSRF-Lite.0.6.tar, WSRF-Lite.0.5.tar.gz, WSRF-Lite.0.4.1.tar, WSRF-Lite.0.4.tar, WSRF-Lite.0.3.tar, WSRF-Lite.0.2.tar and WSRF-Lite.0.1.tar.

AJAX, REST and WSRF::Lite
The current version of WSRF::Lite provides support for AJAX by adding support for XSLT, http://www.w3schools.com/css/CSS and JavaScript. WSRF::Lite will also follow more closely the REST style by supporting the HTTP methods GET, PUT and DELETE for WS-Resources. Arjun Sen for his master's project has been able to use this functionality in the beta release of WSRF::Lite to replace existing SOAP based clients with a web browser, see WSRF Compliance and AJAX.
To learn more about using AJAX with WSRF::Lite see Arjun Sen's Master's Thesis, in which he replicates the functionality of RealityGrid steering client using AJAX and a Web Browser, or look at the 'Using Ajax with WSRF::Lite' tutorial.
