Adding overlapping annotations

[mochar]

Hi. A nice addition to RightField would be to enrich the RDF by for instance being able to refer to a number of triples at once. An example would be having three adjacent, related cells annotated separately, but have an additional validation to annotate them as a whole.

An issue I foresee is that the code assumes independence of validations. For example, when the currently selected cells are annotated, the intersecting validations are removed: https://github.com/myGrid/RightField/blob/master/src/main/java/uk/ac/manchester/cs/owl/semspreadsheets/model/OntologyTermValidationManager.java#L89

I am not familiar enough with the codebase to know the consequences of removing this step. Of course how this will be presented in the GUI is another issue as well. In my understanding such an implementation is quite involved and would take a bit of an overhaul.

What are your thoughts regarding this?

Does this refer to being able to link cells, something that been long needed. For example to say a group of cells relate to another cell, such as describing an assay - rather than the rdf referring everything back to the data file ?
