In general, my guidance has been to use open source mobility frameworks, PhoneGap for cross-platform, Bootstrap for Responsive Web Design, Angular for templating, and some form of OAuth2 for security, at least until the vendor solutions from IBM, Oracle, et al reach a higher level of maturity, since these are stepping stones.
If you look at the latest Gartner quadrants for enterprise mobility and cloud for the previous year, you will see IBM maturing in the MADP space and Oracle maturing in the cloud space... but maturity in both areas is necessary for enterprise mobility to fire on all pistons.
Worklight does three things really well:
- Integrating with existing Websphere and SAM infrastructure.
- Increasing productivity through modularization and emulation.
I have mentioned previously how much I like Worklight's lightweight Rhino-based adapters. They are intentionally lightweight, eschewing any sort of SOA reusability. A Worklight adapter does one thing, and it does it well. This can be initially quite pleasant, then very frustrating, and then liberating, as you sort out how much integration you need to do in your client applications. My experience has been that a well designed piece of XSL can convert an XML data source into some standards-compliant JSON, and then a client-side library service can take it from there.
Granted, the development process is not that easy, and let's consider now that we have a number of data sources, some of which are NIEM compliant, some of which are HL7 compliant, some of which are based on direct SQL access, and some of which are ad hoc.
When you look at the various Worklight adaptation examples, you might get the idea that RSS is treated preferentially, which is untrue; however, thinking of these adapters as syndication is still a useful approach.
The client-side service that I have written - using Angular for modularization - is responsible for merging multiple Atom streams. Once I have a single Atom stream, data-binding takes place, so that information can be presented. In practice, this can be frustrating because Atom is intended for serialization of information, but an Atom bundle can also contain relative links between entries. This is fundamental to the way HL7 FHIR works, but not NIEM, so I have ended up creating synthetic and essentially schemaless resources as necessary. Ideally, all information could be mapped into Atom-syndicated FHIR resources. Maybe that's a good project for this year.
Adaptation frameworks always run into a problem based around the decision to go lightweight or go modular. I like that Worklight has gone lightweight, but I am frustrated that I can't reuse just a little bit more code between adapters. In particular, I would really like to use a single set of XSL transforms to support multiple adapters. Perhaps there is a way to do this, but for now, I am still forcing myself to prune my adaptation code as much as possible to keep it easy to maintain. If I find myself using the full set of DocBook or DITA transforms in an adapter, it's probably time to rethink my approach.
Unless, of course, the platform was also a framework, which is what approaches like Meteor promise.
