What's the rule defining BlockAttr and GenePartsSO?

[viktorxia]

Dear developer(s), in README two fields "BlockAttr" and "GenePartsSO" but I didn't find these formats in other databases. The GenePartSO I guess should be a concept similar to "Sequence Ontology" but they are different in format (SO terms looks like "SO:0001819"). For BlockAttr I just cannot figure out what is it. Could you explain more about how could they were defined and in what way can I update configurations by myself (such as update ncbi annotation database from 104 to 109) ?
