Following on from my earlier Client Handle Demo post, this entry is just to mention the availability of a port of (part of) the Handle client library (in Java) to JavaScript: openhandle-0.1.1.js which is being maintained on the OpenHandle site. The JavaScript module contains methods for three classes: OpenHandle, HandleValue and AdminRecord.
What does all that mean? It means that Handles and their constituent values and value fields can be accessed directly within **any Web browser (using an OpenHandle service) which allows a dynamic Handle client to be generated and presented within a user context. No plugins required. The port mirrors the class methods in the standard Java client library for Handle.
As a demo of this JavaScript module in action, see this Inspector app for a card index view of Handle (and by implication DOI) records.
