Sergey Beryozkin commented on TIKA-1607: ---------------------------------------- Hi, IMHO it indeed makes sense to keep the existing Metadata methods that return String values but also offer an optional support for representing Metadata as a multivalued map of arbitrary object key/values where the original String to String[] pairs are converted into something more sophisticated if required... By the way, JAX-RS API has this interface: http://docs.oracle.com/javaee/7/api/javax/ws/rs/core/MultivaluedMap.html Not suggesting to use natively in Tika, but it might be of interest... Cheers, Sergey > Introduce new HashMap<String, Object> data structure for persitsence of Tika > Metadata > ------------------------------------------------------------------------------------- > > Key: TIKA-1607 > URL: https://issues.apache.org/jira/browse/TIKA-1607 > Project: Tika > Issue Type: Improvement > Components: core, metadata > Reporter: Lewis John McGibbney > Assignee: Lewis John McGibbney > Priority: Critical > Fix For: 1.9 > > > 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.
