The JISC-funded extension of the STARGATE project has released the STARGATE Extension Final Report.
Here's an excerpt from the original STARGATE project page that explains its goals:
The Centre for Digital Library Research (CDLR) at of Strathclyde set out to implement a low-tech solution to OAI-based disclosure for small publishers. Their STARGATE project was based on the 'static repositories' model for using OAI-PMH . . . Instead of building an OAI-compliant repository, a publisher builds a static repository, effectively an XML file of the relevant metadata on an accessible server. A separate static repository gateway handles the technical aspects of making the metadata available for harvesting, i.e. the complexity is shifted away from the publisher.
Here's an excerpt from the report's "Executive Summary":
The extension has produced a functional branded gateway that the publishing community can use to explore the use of static repositories. It will be maintained for the next year. The gateway is available at http://stargate.cdlr.strath.ac.uk/gateway/.
The project concludes that although functional the software is not suitable for deployment by a novice user. It is also effectively still in at the beta stage of development and it has only been used in a limited number of settings.
The project further suggests that the creation and maintenance of gateway(s) within the publishing community may be more suitably carried out in the same way that DOI and Purl provision is offered through a third-party service provider willing to work with developing open source software. Any deployment of a gateway by JISC to support wider participation in static repositories should also engage with the gateway software developers.
