Registration

The identifiers section describes the composition of a globally unique open contracting identifier. On this page you can request an ocid prefix, and can submit details of your published data, as well as checking existing prefixes

OCID Prefix

We are in the process of establishing a self-service registration system for OCID prefixes. In the meantime, to request an OCID prefix please e-mail data@open-contracting.org with the name of your organization.

OCDS does not have a registry of datasets. The approach for data discovery is described in the publication patterns section of this documentation.

However, during this initial phase of OCDS we encourage publishers to share details of their data on the mailing list, and we will explore opportunities to work with the community on maintaining tools to support discovery of data.
