Tim Allison commented on TIKA-1607:
-----------------------------------
Y, probably. We could add limits on length although we're not currently doing
this with Metadata String values. To be fair, of course, I realize that
embedded binary metadata objects (XMP/XFA...) are typically longer than regular
metadata values.
What else is in the can?
Or, is this just a plain bad idea?

> 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
