Implementation of ObjectResolver for a Fedora repository. This implementation will attempt to load a properties file with the name FedoraResolver.properties. Required properties:

formatsDatastream

The id of a content model object's inline XML datastream which describes the unAPI formats available for a Fedora object, e.g. UNAPI-FORMATS

The formatsDatastream must return an XML document that contains a JSON array describing the available formats. For example:

<json>
[["info:fedora/*/DC","oai_dc","text/xml","http://www.openarchives.org/OAI/2.0/oai_dc.xsd"],
 ["info:fedora/*/demo:dc2mods.sdef/transform","mods","application/xml","http://www.loc.gov/standards/mods/"]]
</json>

The above is a JSON array of arrays surrounded by <json> tags. Each four-element inner array represents a single unAPI format. The first element is the dissemination type URI which will requested object in the requested format. The remaining three elements are the unAPI format, type and docs.
