----------------------------------------------------------------------
The - on demand - inclusion of this could be implemented by using STANBOL-488 -
EnhancementProperties - on a per-request base.
But this would bypass the now preferred multi-part content item API. With this
functionality the intended way for get the plain text content is use the
multi-part content item RESTful API extension to request specific content parts
of ContentItems. I am currently working on a detailed documentation on that
with a lot of examples for typical use cases (including this one). The Web UI
of the Enhancer already includes a description of the RESTful services.
In general I do not understand the mention of SPARQL, because the Stanbol
Enhancer does not store enhancement results and therefore can not provide a
sparql endpoint. If this refers to the SPARQL endpoint of the Contenthub, than
you might want to have a look at STANBOL-471. This would allow to have a SPARQL
endpoint on top of (S1) - the store that contains enhanced content items.
As part of the work an STANBOL-471 I will also provide an LDPath wrapper for
ContentItems. This will also have access to the "contents" of the contentItem.
A simple LDPath command like
nie:plainTextContent = fn:content(".","text/plain");
would than take the content stored in the current contentItem with the mime
type "text/plain" and index/store the value with the property
nie:plainTextContent
