Service Description

The Resource Oriented Architecture (Web Services) interface provides ways for web-based clients to perform collocation queries.

References

ROA Layer API

RESTful service methods for invoking the Collocation Service via HTTP.

 

Base URLs

It is assumed in this documentation that no centrally-run instances of the Bamboo Services Platform will be running after the project ends on 31 March 2013. Therefore, base URLs are assumed to be on a developer's machine, localhost. The base URL with a port number assumes that the BSP is running unsecured; the URL without a port number assumes that security is enforced and Apache Web Server is intercepting and redirecting service calls. Please see the page Identity and Access Management - Authentication and Authorization for context, as well as links to installation and configuration instructions for secured instances of BSP.

Note that ONLY services at v0.9 or greater will run properly in a secured instance of the BSP.

Currently available base URLs:

 



 

HTTP Headers and Output Formats

The service supports the following values in the HTTP Accept header:

  • application/xml

Output will be serialized accordingly.
