The SAON Data Portal is a metadata driven data portal. This implies that data are hosted and served by contributing data centres which expose discovery metadata on the datasets. Once initiated, the SAON Data Portal regularly (once daily) harvests discovery metadata from the contributing data centres and ingests this in the SAON Data Catalogue which is integrated in this site. Provided the data is provided in the appropriate form (encoding) the SAON Data Portal is developing software to transform and combine datasets.

In order to connect your data centre to the SAON Data Portal an OAI-PMH (link is external) or OGC CSW end point serving either GCMD DIF or ISO19115 discovery metadata is required. If ISO19115 is used, discovery metadata should include GCMD Science Keywords to describe the parameters measured. If your data centre is hosting much data and SAON relevant data is mixed between other data, a dedicated OAI-PMH set is welcome to simplify the harvest process for the portal.

Support for other technologies (e.g. OpenSearch, DCAT, are under development.
