Reach (http://www.reach.ie) is an agency established by the Government of
Ireland to develop a strategy for the integration of public services and to
develop and implement the framework for electronic government. In
particular, Reach is mandated to procure and build the Public Services
Broker (PSB), which is an integrated set of processes, systems and
procedures designed to provide a standard means of access to public services
Technically speaking, the PSB is a hub based, asynchronous XML messaging
infrastructure. Some people would call it a Services Oriented Architecture.
Anyway, XML messaging is a critical part of the PSB and interoperability
across systems and platforms is a major concern in the architecture.
To that end, Reach have created a website dedicated to XML messaging and
interoperability known as the Services and Data Exchange Catalog (SDEC):
Guidelines for XML interoperability are known as RIGs (Reach
Interoperability Guidelines). The current RIGS are published on the SDEC at
Of particular interest to xml-dev folks:
RIGs 2 (XML) (http://sdec.reach.ie/sdec/rigs/rig0002)
RIG 3 (namespaces) (http://sdec.reach.ie/sdec/rigs/rig0003),
RIG 4 (Schema languages) (http://sdec.reach.ie/sdec/rigs/rig0004)
RIG 5 (Unicode) (http://sdec.reach.ie/sdec/rigs/rig0005)
RIG 6 (Versioning) (http://sdec.reach.ie/sdec/rigs/rig0006)
RIG 12 is an overview of the interoperability rationale that underpins the
other RIGs. (http://sdec.reach.ie/sdec/rigs/rig0012) and would be a good
RIG to read first.
The RIGS are maintained as OpenOffice documents. PDF and Word versions are
exported from the OpenOffice source.
We are working on a down-translate from the OpenOffice to nicely
For more information about the PSB, see http://www.reach.ie/publications/#psb.
Comments/bug reports on RIGs are welcome.
If you wish, you can send comments directly to Reach. Each of the RIGS has
e-mail addresses in the front matter.
Also, a mailing list has been set up for public discussion
