Hi all,

to find out if documents are changed, within ops and CQL, I only can use the publication-date.
However, documents may change without a publication-date change.

In docdb examples there are essential fields I'm missing within OPS and, supposed OPS would
provide them, could help to reduce the efforts to find changes.
(e.g. "date-publ" : "20080703",
"is-representative" : "YES",
"date-of-last-exchange" : "20170622")

"date-of-last-exchange", "date-of-previous-exchange" and "doc-id" are all helpfull fields to find

Is it possible to extend the OPS CQL / results with at least a "date-of-last-exchange" ?

Regards, Martien

OPS is not fed by DOCDB this is why it also has less records loaded then DOCDB does.
This is also a reason why this information is not and cannot at this point added into OPS. OPS is fed by EPODOC, same as Espacenet
