post composition annotation

Page to write about the post composition of annotations for data in supplemental .ttl files.

I had been experimenting with post com-positionally creating annotations, for example for the global_chlorophyll_a.csv dataset, when annotating a data column about haptophyta chlorophyll a, instead of making a new class for haptophyta chlorophyll a, I made a blank node by which to annotate the column. The blank node works and is parsed into the conjunctive graph in a python script.

#HaptophytaChlA column is about an owl class which is a subclass of chlorophyll a and is part of some Coccolithale
file:HaptophytaChlA obo:IAO_0000136 _:b4 .

_:b4 rdf:type owl:Class ;
	rdfs:subClassOf obo:CHEBI_18230,
		[obo:BFO_0000050 obo:NCBITaxon_418917] .

which is parsed into the datastore graph and expressed in ttl as:

ns1:global_chlorophyll_a.csvHaptophytaChlA rdfs:label "Haptophyta Chl A" ;
    obo:IAO_0000136 [ a owl:Class ;
            rdfs:subClassOf [ obo:BFO_0000050 obo:NCBITaxon_418917 ],
                obo:CHEBI_18230 ] ;
    ns2:rfc4180columnPosition 7 .

See the end of the log from this day: 28.11.17.

//TODO:

I need to check if I can query for a data about this column using the blank node annotation.

What I'd like to do is post-compositionally annotate classes to be in the same format as is done by owl to add annotation properties to it's classes. This way querying against ontology and querying post-compositionally annotated data can be done in the same way, which makes my scripts more standard and powerful.

worked on this see log from 08.12.17

Also worked on it this weekend see logs from: 09.12.17, and 10.12.17
