Maciej Lizewski commented on CONNECTORS-657:
--------------------------------------------
Unfortunately last-modified is sent to output connetors as it is added to
RepositoryDocument with 'addField' in processDocument and all such fields are
sent to output connector. Maybe most indexes ignore this attribute, but my
configuration does not... I am ok with different timestamp formats used to
create version strings, only those sent as metadata to output connectors make
difference.
If we choose to extend RepositoryDocument, I recommend we should allow to add
any field as Date object, i.e.:
doc.addField( "last-modified", new Date() );
doc.addField( "created", new Date() );
and then in OutputConnector you can cast it to string, format, or do whatever
needed for connected index before posting. Anyway - if we add Date type fields
(in general or only lastModified) there will be also incompatibility because
you will have to drop value passed as "lastModified" and use only this passed
as special attribute in RepositoryDocument...

> Components: Framework crawler agent

> Fix For: ManifoldCF 1.2

>
> several connectors add datetime attributes to RepositoryDocument, but they do
> not have common format. Examples:
> WikiConnector adds last-updated: 2010-10-10T12:34:00Z
> SharedDriveConnector adds last-updated: Thu May 28 17:39:46 CEST 2009
> and so on.
> Solr requires all date/datetime fields to be passed as YYYY-MM-DDTHH:II:SSZ
> We need to standardize formats (my recommendation is solr format) or allow to
> add Date attributes to RepositoryDocument and move formatting to
> OutputConnector.
