[Yanel-dev] Annotating resources

[Michael Wechner]

Hi

Thanks to Marc Schaaf we now have an "Annotatable" interface which 
allows to annotate resources
and also use this information for third party applications, e.g. Boost 
in order to generate tag clouds re what users are interested in. Marc 
has also created a simple annotation editor which is currently used by 
the yanel website realm.

I guess Marc will send some more notes re further steps (e.g. re 
ontologies: http://en.wikipedia.org/wiki/Ontology_%28information_science%29)

The basic code pieces are:

U    conf/resource-types.xml
A    
src/realms/yanel-website/res-configs-repo/data/usecases/pageMetadataManager.html.yanel-rc
U    
src/realms/yanel-website/src/java/org/wyona/yanel/website/menu/impl/YanelWebsiteMenu.java
U    src/realms/yanel-website/data-repo/data/xslt/global.xsl
A    src/core/java/org/wyona/yanel/core/api/attributes/AnnotatableV1.java
U    
src/resources/xml/src/java/org/wyona/yanel/impl/resources/XMLResource.java
A    src/resources/pageMetaDataManager
A    
src/resources/pageMetaDataManager/src/java/com/wyona/yanel/metadata/manager/PageMetaDataManager.java

Re code review:

    * Does it build? YES
    * Is the formatting correct? Should be fixed now (used tabs instead
      of spaces)
    * Is there an automatic test? Make sure that there are automatic
      tests, which are covering the changes which the patch will imply. NO
    * Is it backwards compatible? YES, because annotations are
      implemented as a versioned interface
    * Does it scale/perform? (Can the implementation be changed?) YES,
      because of doing it as an interface
    * Can it be enhanced? YES, because of versioned interface
    * Can it be customized? The implementation can be customized
    * Does it work within a cluster? NOT really, because the properties
      are not locked yet, but we will fix that shortly. But also depends
      on the repository implementation.
    * Is it secure? YES, if the policies for the editor are set
      correctly, but NO otherwise
    * Can it be used offline? YES
    * Can the patch be reverted easily? NO, because various resource
      types (e.g. XMLResource) will start implementing this interface
    * Does it work for all browsers? Only tested Firefox yet

Cheers

Michael
