Deploying Data Services and Data Service Resources

Deploying and exposing a data service resource via an OGSA-DAI WSI data service is a three-step process. These are described in more detail on the following three pages.

1. Deploy an OGSA-DAI data service. This data service initially exposes 0 data service resources.
   • Data services can expose 0 or more data service resources. It is up to you whether you expose 1 data service resource per service or expose multiple data service resources per service. It may be useful to consider whether you intend to restrict access to your service (make it secure) since this will, of course, restrict access to every resource exposed by that service.
   • See Deploying data services.
2. Deploy a data service resource. The data service resource contains information about a data resource and the activities clients can perform on that data resource via a data service.
   • See Deploying data service resources.
3. Instruct a data service to expose a data service resource thereby allowing clients to interact with it.
   • See Exposing data service resources via data services.

If you are using the OMII platform you may also wish to:

1. Enable OMII message-level security on a data service. This enables secure calls to your data service running on an OMII platform.
