  • Located in southern norway. <br /> <br /> <br />
  • Stability, predictability, maturity <br /> Stability often comes at the cost of innovation. We cannot do all that much fancy within the scope of Plone 3. That would break the promise. <br /> So, as happy as we are with Plone 3 — time to get innovating again. <br /> <br />
  • Build Plone 4 and put plone back on the cutting edge. <br /> <br />
  • was called Plone 4 <br /> Planned a big release with massive changes in 2010 <br /> But as work progressed, it became evident that there was quite some release-worthy stuff that wouldn’t have to wait for such a major overhaul — and till 2010. <br />
  • So it was decided to make a Plone 4 release, hopefully in 2009 <br /> Not as radical as the work on Plone trunk <br /> Will have new features, — but stuff that is stable now. <br /> Features that are too big for a 3.x release. (i,.e require migration, compatibility changes, might break addons) <br /> Not experimental <br />
  • With release manager Eric Steele , who should take special care to make sure there are more high-resolution images of him available on the web. <br />
  • All the big changes that were recently referred to as Plone4. Are now called Plone Trunk. <br /> Hopefully a 2010 release as Plone 5. <br /> Hanno will be release manager for Plone 5. <br />
  • <br />
  • As there is a formal proposal and review process, code to be written on a volunteer basis, and a general lot of uncertainty here — let’s see all of this as speculation, guesswork and hopes. <br /> <br />
  • <br />
  • <br />
  • Widely used visual editor. <br /> Kupu is no longer maintained. <br /> The new editing UI for Plone trunk will also be based on TinyMCE. <br /> Plone integration already. <br /> You will still be able to use Kupu with Plone 4, of course. We’ll just switch the default. <br />
  • Finally proper support for BLOBs <br /> Store binary objects outside the ZODB <br /> On the filesystem <br /> Tested. We have this running in a 7000 employee intranet. <br />
  • btree-based folder implementation <br /> faster <br /> scalable <br /> replaces Folder, ATFolder, Large folder etc <br /> <br />
  • Upgrade machinery. replaces the critically dangerous reinstall button in the portal quickinstaller. <br /> Makes it simple for product authors to define upgrade steps between versions. <br />
  • <br />
  • No more need for hacks like this. The builtin Zope mailhost is now more advanced than this one. It is better for us to have less custom stuff to maintain. <br /> <br />
  • <br />
  • Newbie (limited/restricted user) <br /> Site admin vs Manager <br />
  • Stuff like Gloworm <br /> <br />
  • Debugmode should be linked to Zope’s debugmode. <br /> <br /> Major source for confusion for newbies. <br />
  • Commenting is one of the original cool features of the CMF and Plone — but it is way overdue for revision. <br />
  • <br />
  • … so the recently updated plan shows a timeline like this, with a <br />
  • <br />
  • <br />
  • <br />
  • <br />
  • <br />
  • <br />
  • Tiles is the back-end architecture <br /> Deco is the front end editing interface <br /> <br /> <br />
  • <br />
  • <br />
  • <br />
  • <br />
  • By having the editing controls clearly separate from the rest of the UI, it makes it obvious to users where to find editing controls. <br /> It also makes it easier for us to build more advanced menus, as we don’t have to take theming stuff into consideration. <br /> Much simpler job for themers. <br />
  • Not needed anymore. <br /> Since deco handles layout properly <br /> no more need for “use content as default page” <br /> <br />
  • <br />
  • Plone looks rather old and worn by now. <br />
  • …So Alex Limi is working on a freshup to the new default theme <br /> … based on the typography and overall feel from Plone org. <br />
  • <br />
  • <br />
  • <br />
  • Archetypes will still work <br /> Dexterity will be there for those that want to switch <br /> And if you don’t need types, you’ll not have to relate to either. <br /> <br />
  • <br />
  • <br />
  • <br />
  • <br />
  • <br />
  • <br />
  • <br />
  • Templating engine — can be used for multiple syntaxes of attribute based languages like ZPT and Genshi <br /> Quite faster. Maintained, <br /> Used by Repoze.BFG, Pylons, Plone <br /> <br />
  • <br />
  • <br />
  • <br />
  • Collective.SOLR integrates with SOLR, an open source enterprise level search engine — much more advanced than ZCatalog. <br /> We have used this in a 7000-employee intranet we deployed last year. It works wonderfully. There is no way ZCatalog could have handled the load and the amount of content. <br />
  • <br />
  • <br />
  • Replacement for Archetypes. <br /> <br />
  • <br />
  • Theming fast and simple. Write html, poke holes in it for your Plone content. There are a lot of talks on Deliverance at this symposium. Catch at least one. <br /> XDV is deliverance reimplemented as compiled XSLT. Currently has less features than deliverance, but has much better performance. Laurence’s goal is to have it compile down to a single XSTL transform that can be placed in the pipeline. No special software required to host it. Developed and used. Used on Plone.org. <br /> <br />
  • <br />
  • These are by far the most common tasks a developer will need to perform. <br /> plone.Grok directives for these common scenarios. No more need for zcml. <br />
  • Get rid of portal_properties <br /> split more tools into configuration and functionality <br />
  • (assuming plone trunk will be named Plone 5) <br /> There are currently no in-place migration to Plone trunk (like we have in previous Plone versions) <br /> <br />

  • Performance
  • Simplicity
  • Tiles/Deco A new approach to page editing
  • Pages: Layouts composed of tiles
  • Tile Persistent Stores con guration …and (optionally) data Form for con guration Lives at an unique URL Renders to HTML
  • Example tiles HTML text Image with caption Dynamic list of elements (f.ex news) Flash movie/app Form, poll etc. File download Archetypes/Dexterity elds

  • …even an event
  • Not the end of content types Custom types still have many usecases
  • Choice of types Dexterity or Archetypes or NONE
  • Performance Plone needs to be faster…
  • Plone needs to be faster… …out of the box …for logged in users …in high-end scenarios
  • Reduce and simplify the codebase
