vo@astron.nlData retrieval This service delivers (most of) the datasets held at The VO @ ASTRON. In addition to the default (nonstandard) way of just appending accrefs to the get access URL, there is also a very simple datalink service here that, for each dataset, essentially just gives the dataset itself and possibly a preview. More advanced datalink services might be available. Some datasets may be embargoed, in which case the access yields a 403. Credentials for individual files may be obtained by contacting the site operators.https://vo.astron.nl/__system__/products/p/infohttps://vo.astron.nl/getproducthttps://vo.astron.nl/__system__/products/dl/dlmetaGETapplication/x-votable+xml;content=datalinkIDThe pubisher DID of the dataset of interestmeta.id;meta.maincharRESPONSEFORMATFile format requested for output.meta.code.mimecharMAXRECMaximum number of records returned.

It is normally fed through the products#define rowfilter and a mixin like products#table (or other mixins using it like siap#pgs or ssap#mixc). /getproducts inspects this table before handing out data to enforce embargoes and similar restrictions, and this is also where it figures out where to go for previews.accrefAccess key for the dataAccess.ReferencecharindexedprimaryownerOwner of the datacharnullableembargoDate the data will become/became publicacharnullablemimeMIME type of the file servedmeta.code.mimeAccess.FormatcharnullableaccesspathInputs-relative filesystem path to the filecharsourcetableName of table containing metadatacharindexedpreviewLocation of a preview; this can be NULL if no preview is available, 'AUTO' if DaCHS is supposed to try and make its own previews based on MIME guessing, or a file name, or an URL.charnullabledatalinkLegacy column.
