Ray Gauss II commented on TIKA-1607:
------------------------------------
Sorry, I meant {{EmbeddedDocumentExtractor}} (edited comment).
We can currently dump stuff to files in some parsers with the {{--extract}} CLI
option which sticks a {{FileEmbeddedDocumentExtractor}} in the context.
The current default for PDF is the {{ParsingEmbeddedDocumentExtractor}}.
Perhaps we could add an option to ParsingEmbeddedDocumentExtractor which, when
enabled, would also save the embedded resources in memory for an advanced user
to do whatever they need, knowing the risk and resources required for that
option?
Or provide some other in-memory implementation that advanced users could
explicitly set in the context?

> I am currently working implementing more comprehensive extraction and
> enhancement of the Tika support for Phone number extraction and metadata
> modeling.
> Right now we utilize the String[] multivalued support available within Tika
> to persist phone numbers as
> {code}
> Metadata: String: String[]
> Metadata: phonenumbers: number1, number2, number3, ...
> {code}
> I would like to propose we extend multi-valued support outside of the
> String[] paradigm by implementing a more abstract Collection of Objects such
> that we could consider and implement the phone number use case as follows
> {code}
> Metadata: String: Object
> {code}
> Where Object could be a Collection<HashMap<String/Property,
> HashMap<String/Property, String/Int/Long>> e.g.
> {code}
> Metadata: phonenumbers: [(+162648743476: (LibPN-CountryCode : US),
> (LibPN-NumberType: International), (etc: etc)...), (+1292611054:
> LibPN-CountryCode : UK), (LibPN-NumberType: International), (etc: etc)...)
> (etc)]
> {code}
> There are obvious backwards compatibility issues with this approach...
> additionally it is a fundamental change to the code Metadata API. I hope that
> the <String, Object> Mapping however is flexible enough to allow me to model
> Tika Metadata the way I want.
> Any comments folks? Thanks
