[ http://issues.apache.org/jira/browse/GRFT-25?page=comments#action_66827 ] Christophe Lombart commented on GRFT-25: ----------------------------------------
Comments <CL> for <DST> comments :-) <DST> I use getProperties only. When you say title, description, and owner should not be mandatory, are you saying to move them to properties? <CL>Yes, I propose to move them to the new Document interface (description & title). For me, owner is too specific. I can imagine to build a DM application without the need of this attributes. I would like to make another proposal on how to extend the Grafitto model and organise the project on severals modules. I'm going to post something today. 5. It is difficult to extend the model. <DST> well it requires writing Java code, but it hasnt been that difficult from the Java POV <CL> correct and we can write a maven pluging used to initialise a new Graffito module ? In fact, a module can be used by an Graffito user in order to extend the Graffito model, add services or customise a core module. > PROPOSAL : New Graffito Object Model > ------------------------------------ > > Key: GRFT-25 > URL: http://issues.apache.org/jira/browse/GRFT-25 > Project: Graffito > Type: Improvement > Components: Model > Versions: 1.0-a1-dev > Reporter: Christophe Lombart > Assignee: Christophe Lombart > Fix For: 1.0-a1-dev > Attachments: graffito-model.png > > Introduction > ------------ > This document describes a proposal for a new Graffito Object Model. > In my point of view, the model has the following weaknesses : > 1. The CmsObject interface contains too many attributes. Title, description > and owner should be not mandatory. Futhermore, this interface contains > getObjects() and getProperties() which could be duplicate attributes. > 2. The Document interface forces to have a binary content. Binary content is > only interesting for Document management & asset management. We can expect to > use Graffito for a CMS application containing only articles. In a such case, > an article can be composed only of a set of String : title, summary, content, > authors, ... and not binary content. > 3. The Content interface is not an appropriate name. DocumentStream seems to > be more explicit. > 4. We need to have a better internationalisation support. > 5. It is difficult to extend the model. > The New Object Model > -------------------- > The proposed model is splitted into different modules (see in attachement the > UML class diagram) : > * The Graffito code module. > * A series of optional modules. > 1. The Graffito Core Module > --------------------------- > This module contains all ancestor objects like CmsObject, Folder, Content. > Content is the ancestor of any kind of content object (Document, topic, > article, ...). Versionning is not mandatory is all case. The > "VersionnedContent" is the ancestor used in a version management context. As > you can see, only content can be versionned. Later, we can support > versionning on Folders. > 2. Optional modules > ------------------- > Depending on the application requirements, the Graffito users can select one > or more optional modules. If the Graffito model doesn't fit to the > application requirements, it should be possible to plug a customized module. > One subproject per module has to be defined in the Graffito project. > 2.1 Document Management module > ------------------------------ > This module manage any kind of binary documents (Ms Word, pdf, ...). By > default, this DM module is supporting internationalisation. In order to > increase the performance, the DocumentStream should be defined as a proxy. > All documents are versionned. > 2.2 Article Management module > ----------------------------- > This module can manage translated articles or single language articles. All > articles are versionned. > 2.3. Forum > ---------- > This module is a simple object model that can be used for a Forum > application. Obviously, topic (the forum content) are not versionned. > 2.4. Other modules > ------------------ > Now, it should be easy to extend the Core Graffito module or any other > optional modules. For example, someone can add a news management, asset > management or customize the article module. > > 3.Open points > -------------- > * Review the project structure in order to support modules. > * CmsObject interface : getProperties, getObjects() : David, are you using > both attributes ? > * Internationalisation : providing by default in the different module or not > ? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
