In the Lovely projects we use zc.relationship, even though it is much more complicated than it should be. That seems unnecessarily derogatory. :-) But I know where you are coming from. As the author, I'd say more low level than most people want. The low-level interface--the index--is precisely what I needed for the projects for which it was developed. The containers in the relationship package were experiments at a more friendly wrapper. Other friendly wrappers that constrain the capabilities in exchange for the greater ease of use found in packages like the zc.schooltool code have been threatened by others. That would be great. Meanwhile, I am as sure as I can be without having used it myself that the zc.schooltool relationship package is easier to use for common use cases. If you need something more flexible, you may want to look at the zc.relationship index. Gary ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Links / Relationships (again)
Howdy. What is the state of various relationship / link managers for Zope 3? A year ago we banged out a quick idea that used Int IDs to track links (mostly to generate in-site URLs) to target objects. And then we ended up copying and pasting the code across a lot of projects. I'm wanting to clean that up by, perhaps, implementing a widget. But I'm wondering if there's a better way to track references to targets. A source object might be a banner ad or promo button with a link to some other internal object like a page with more details. For one customer I made a Schema field and a Property that used schoolbell.relationship (probably from a quite old version of Schoolbell) but made it basically as easy to use as what I could figure out from zope.agxassociation, which doesn't appear to be finished. Basically I generated the Triple that schoolbell.relationship requires automatically using interface/field names to make the URI. (I don't think in RDF, so I wanted that aspect to be as invisible as possible). I don't know whether I should reuse what I made there, or if there were some other viable options. Basically, I would like there to be a way that I can easily query an object to see if there are any links pointing in its direction so that I could handle a Delete operation. IE - Deleting the Summer Sale page will break the following items: (1. Summer Sale Promo, 2. Summer Sale Newsletter Banner). Do you want to delete those as well? .. or something like that. It's a bit beyond the scope of my current project, but is something I'd like to get back to. I see there's a `zc.extrinsicreference` in the svn.zope.org repository. Is that in a usable state?

As Benji said, yes, and it sounds like it might fit your use cases. You might be interested in http://mail.zope.org/pipermail/zope3-users/ 2006-July/003950.html and ff., if you didn't read it already, to clarify our/Jim's concept of when to use what kind of relationship tool.
