What is the activity function's return type?

[abargnesi]

BEL 1.0 declared abundance as the return type for specific activity types (e.g. kinaseActivity). This implies that the following is semantically valid:

complex( kin( p(HGNC:JAK2) ) )

Given the following function signatures of kinaseActivity and complexAbundance:

kinaseActivity(F:proteinAbundance)abundance
complexAbundance(F:abundance...)abundance

---

Does this hold true for BEL 2.0's general-purpose activity function?

[ncatlett]

complex( kin( p(HGNC:JAK2) ) ) should NOT be semantically valid. Maybe this is a mistake in the BEL 1.0 implementation?

[abargnesi]

Yeah it looks that way. Here was my experience running this through the BelCheck tool.

Thanks for the clarification. We will make sure to correct the semantics in BEL 1.0 & 2.0 implemented in OpenBEL/parsers.

We may want to consider a patch to OpenBEL Framework.
