As NBS currently offers two interfaces to data, there are some differences in the machine interfaces between them. The DHUS software offers OpenSearch and Open Data Protocol (ODATA). The NBS test portal offers OPeNDAP, OGC WMS, and ODATA (through the DHUS interface). OAI-PMH is under implementation and configuration. OGC WCS and OpenSearch is under consideration and planning for the test portal.
