Adding Custom metadata dynamically through Java Found API

pramodkhare — Tue, 14 Aug 2012 16:00:04 GMT

I am new to Alfresco development. So please need help with this.Hi currently I am developing web-UI in ExtJS for Alfresco 4.0 using Java Foundation API. Our total application is really big and we want to build a Document Mgmt Module, so we are using Alfresco at backend as doc-repository.Basically, I

You will still have to create the XML, but you can do that with code. Instead of putting the content model on the file system, which would require a restart, put it in the data dictionary. See http://wiki.alfresco.com/wiki/Dynamic_Models#Dynamic_models.

Really Thanks Jeff.

I need to ask few more things, -

1) Basically I want to add custom-metadata i.e. Properties to a document (properties which are not specified in my content model), apart from new Aspect/Content Model Creation, is there any other way of doing this?? i.e. Adding custom properties to a content (maybe through Java Foundation API beans).

2) I am currently developing a new UI in ExtJS for Alfresco, so I am thinking to use alfresco in embedded deployment mode, i.e. I will connect my controller classes to Alfresco Java Core Foundation API, is this a correct approach? Why because not only my whole application is built in Java, but I want to reduce Alfresco footprints, and avoid unnecessary code also. As you have a lot lot more understanding about Alfresco's structure, I am asking your advice on this.

3) Can you suggest me some books/articles/websites or anythings which will give me more understanding about Java Foundation Services (i.e. Spring beans implementation) for doing my development.

4) I have checked out Alfresco SVN repository completely, but I am confused which projects should I use for my Embedded Alfresco deployment/development. Please suggest regarding the same, where can I find related information.

You can set properties via the Java Foundation API if those properties are already defined in your content model. An exception to that is something called a "transient property", but those aren't documented very well and I don't know much about them. You'll have to hunt around to determine whether or not they will work for your particular use case.

I am a fan of de-coupling the repository from the front-end. Especially if you ever need to scale your solution. You want the flexibility to scale those tiers separately. I wouldn't embed the repository in your application unless you have a very good reason to do so.

3) Can you suggest me some books/articles/websites or anythings which will give me more understanding about Java Foundation Services (i.e. Spring beans implementation) for doing my development.

You'll know what meets your needs better than I will. The best I can do is point you to to the JavaDoc, the wiki, the official docs, and the Alfresco Developer Guide (2008, Packt). Beyond that you'll have to search.

4) I have checked out Alfresco SVN repository completely, but I am confused which projects should I use for my Embedded Alfresco deployment/development. Please suggest regarding the same, where can I find related information.

Look at the First Foundation Client example in the Alfresco SDK Eclipse project.

Good luck!
