[opencms-dev] Semantic CMS

[Rüdiger Kurz]

Hi Jose,

Alkacon as industrial partner of the EU funded IKS project was involved 
in the development of Apache Stanbol which is one of two software 
components that have been invented in the course of the IKS project.

VIE (Vienna IKS Editables) [1] is a JavaScript library for implementing 
decoupled Content Management Systems and semantic interaction in web 
applications. With VIE you can easily interact with RDFa-annotated 
content on your pages, as well as connect with various semantic services 
like Apache Stanbol and DBpedia.

What can easily be done with those two technologies is to send an 
unstructured plain/text document to Apache Stanbol that will return a 
semantically enhanced result containing the found entities.

Because OpenCms is using XSD schemas to define the structure of the 
contents it is really not complicated to write JSPs that are generating 
annotated content. So you could think about annotating the HTML produced 
by OpenCms e.g. using schema.org and RDFa, what will enable you to let 
Stanbol extract your own entities that can then be used as vocabulary or 
categories or be stored in the entity hub.

This is a very powerful approach because you can depict a company 
specific category hierarchy and/or wording as entities on a Stanbol 
server instance. Once your own entities are stored in Stanbol, you can 
link your content automatically or make other semantic analytics based 
on the customer specific requirements.

However Stanbol as a top-level Apache project will be a good staring 
point to semantically enhance OpenCms not at least because the 
technology stack is quite similar.

There exists a demo from Alkacon at [2] that shows how to retrieve 
images that are related with a text written with the TinyMCE editor. 
This demo uses a Stanbol Server that can be accessed at [3].

Kind Regards,
Rüdiger.
