Restrictables
The following keywords may be used as restrictables in TAP-VAMDC queries using VSS1 language,
also they are added to registry for each new node.
Note that each node supports only a small subset of the keywords. The list of supported keywords may be
retrieved through VOSI Capabilities service endpoint. See the TAP-VAMDC documentation for further details.
AsOfDate
Return data excluding any additions or improvements that were made after the given date (YYYY-MM-DD). This allows for reproducing an earlier query. Note that probably not all nodes support this.
