Channeling Chris here: BFG can't truly be said to be a Zope3-derived framework: it doesn't *require* application developers to use the ZCA, altho[ugh it happens to use the ZCA in its implementation (primarily as an optimization at this point). Its dependencies have never included more than a handful of Zope3 packages (zope.interface, zope.component, zope.configuration, and dependencies). Its notions of a view is radically different than a Zope3 view, for instance: in BFG, a view is nearly always just a function or other callable, and only rarely (primarily in migrated code) a class / factory taking context and request and returning a "view object." In 2010, *none* of the Zope3 technologies are "required knowlege" for a BFG developer: you can literally write a BFG app which imports *nothing* from the zope.* namespace at all (nor ZODB and related packages, etc.) Tres. - -- =================================================================== Tres Seaver +1 540-429-0999 tsea...@palladion.com Palladion Software "Excellence by Design" http://palladion.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAktX4w0ACgkQ+gerLs4ltQ4/4ACgiPFOk3OuyTBhlBwaKtPx+xum Gm0AniQd3CzgBLXkzyHP5cWzwWW/JOtp =fsV5 -----END PGP SIGNATURE----- _______________________________________________ Zope-Dev maillist - Zope-Dev@zope.org https://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope )
