CDM Community Server

A Central datastore for a community of users (taxonomically, geographically or otherwise defined). The community store server is used to centrally host versionable CommonDataModel data.

The store makes use of the CdmLibrary and exposes webservices based on the CdmLibrary service layer.

The CDM Community Server is a central piece of the platform and applications that are able to interface with this server are considered part of the platform.

For installation instructions please refer to the CDM Standard Setups


Srvices/APIs exposed by the community store are:


Mainly read operations exposing CdmDataTransferObjects for the CdmDataportal. The services are URL encoded REST services and the http content-type of a request specifies whether XML (default) or JSON will be returned. For further details please refer to CDM REST Services.

The detailed list of implemented and planned operations can be found at wiki:CdmAPI#RemoteAPI

RSS Search feeds

Additionally to the search services provided by the REST API above, the same search methods will also be exposed as RSS feeds. This allows RSS clients, or wikipedia:Aggregator, to "subscribe" to specific searches as RSS feeds are natively ordered chronologically and new search entries therefore can easily be identified. It is planned that all PrimaryCdmObjects will be exposed for searches.


In order to allow central aggregators harvesting the CDM Community Stores the OAI-PMH protocol with selective date based harvesting has been implemented in to the CDM Community Stores. BHL":, "GBIF":, "EOL or any other data aggregator thus are able to easily pool CDM data selectively and keep their copy up to date by accessing incremental changes only.

For more information please refer to CDM Community Server - OAI-PMH


The CDM Store will include an LSID resolver exposing PrimaryCdmObjects objects in RDF as TDWG LSID voc
