datacube-validator issues

hi,

just learned that the gld working group is no longer, am i right here?

i just came a couple of issues with the datacube validator:

1. Every DataSet has a unique associated DataStructureDefinition (true if
there is a problem), query [1]
   => when i run the query against my dataset it returns false, the
validator-gui displays a red X
2. Every SliceKey must be associated with a DataStructureDefinition, query
[2]
  => query against my dataset returns false, the validator-gui displays a
red X
3. No two observations in the same cube may have the same value for all
dimensions, query [3]
  => query doesn't work in virtuoso (6, haven't tested in 7), but this
doesn't look right: BIND( ?value1 = ?value2 AS ?equal),
BIND(sameTerm(?value1,?value2) AS ?equal) works..
4. typo in [4]
=> qb:sliceStructure ?key1, ?key2; must be replaced by  qb:sliceStructure
?key1, ?key2 (removing the semicolon)
