Hi, instead of storing meta-data in EOModel userInfo, we use the d2w-rule-engine to store this kind of information. It's much more flexible.

I’ve been looking at Cayenne as a replacement for EOF and one roadblock I am running into at the moment is support for a userInfo type structure in the Cayenne datamap. Admittedly, it’s been about 6 months or so since I’ve looked, but from what I could tell, this appeared to be an open issue with Cayenne. It looked like there might be some idea on how to implement it at one point, but I did not see any resolution or implementation of it. I make extensive use of the EOModel userInfo dictionary (primarily on entities, but also on properties) to identify things that are configured at runtime. For example, I have a key named “taggable” that drives the template generation of my _EOEntity.java files. I also use userInfo entries to specify information for my auditing framework (e.g. being able to specify whether or an entity is audited, which keys to audit, etc.) or my custom filtering framework (e.g. to be able to turn on custom searches for an entity and to identify the keys that can be used in custom searches). These are just a few examples. My current thinking is to separate this metadata from the model and move it into its own configuration file, but that opens up the risk of the metadata getting out of sync with the model. It also seems a little dirty to me. Curious if anyone else is in a similar position, or has already solved such an issue?

Had parallel branches for a while and then switched in production, never looked back. Cayenne is similar enough that most of the work is either boilerplate conversion or actually making use of the newly-gained benefits. Very few hard problems encountered, and all solved. Let's have a talk in Frankfurt about what your EOF specifics actually are.

In preparation for the coming WODay in Frankfurt, I'd love it if you'd be open to having a discussion on the status and future of WO, so we can enter the coming work prepared. I'd like to begin by sharing my own thoughts on the matter, based on my current stack and experience. It's a rehash of something I posted to our Slack yesterday, may sound revolutionary and will no doubt be controversial, but I think some outside-the-box thinking is required at this time. This is lengthy, sorry about that… -- In the past few years I've been working towards minimising the use and effect of WO/Wonder on my stack, so when and if The Time comes, I and my customers have a migration path forward. Among the things I've done is move from EOF to Cayenne and from Ant to Maven (to make using 3rd party jars, including Cayenne easier), both of which have turned out to have been very happy decisions which I wholeheartedly recommend, regardless of anything else you do. I love working with my WO/Cayenne stack, which is currently only "polluted" by the following frameworks: -- WO: * JavaFoundation (indirectly through WO, I never use foundation classes in my code unless absolutely required by WO) * JavaWebObjects -- Wonder (I consider Wonder "polluted" since it depends on WO/EOF) * ERExtensions (only the WO stuff, not the EOF stuff) • Ajax • WOOgnl (indirectly for parsing Wonder-style inline templates) …and of course then there's the deployment stuff (JavaMonitor,wotaskd, adaptors). Given this, here's my proposal for a way forward: * We abandon EOF (and, in fact, any ORM—this is not meant to be a full stack effort, initially at least) * We re-implement JavaWebObjects as required (and the absolutely necessary parts of JavaFoundation, such as KVC and NSBundle) as a single framework * We separate the necessary WO stuff from the EOF/D2W stuff in Wonder (as well as other totally unrelated things like mail sending frameworks, other utility frameworks and "useful applications") and include it in our re-implementation * We create a fork of WOLips that knows how to live within the New Universe * We rule the world Ideally, what we end with is Just a Web Framework™ with IDE integration (and nothing else) that can serve as a basis for future development. While re-implementing WO may sound like a huge undertaking, I actually think it's smaller than rewriting all of my solutions that depend on it. This probably applies to more of you. Now, looking at my own stack I know this proposal might sound a bit self-serving, but I'd like to hear other opinions. I believe it's a realistic way forward with (comparatively) minimal development effort. Turns out that WOF itself is the only part of the WO/Wonder stack that I really just don't want to live without. This is something I'd like to do, and if anyone likes the idea and is willing to participate, I'm confident we can make this work! Doing stuff alone sucks.
