Consider using HsapDv IDs

[cmungall]

EHDAA2 has stage classes like:

[Term]
id: CS01
name: CS01
namespace: carnegie_stage
is_a: CS:0  ! Carnegie stage

This is problematic for a couple of reasons. These are not well formed IDs because they lack ":"s. Unfortunately OboEdit is forgiving here but this causes downstream issues.

I would recommend using HsapDv here. Each class has more specific info, synonyms, definitions etc. If you are amenable I can swap these out.

Example:

[Term]
id: HsapDv:0000003
name: Carnegie stage 01
namespace: human_developmental_stage
def: "Embryonic stage defined by a fertilized oocyte and presence of pronuclei." [http://embryology.med.unsw.edu.au/wwwhuman/Stages/CStages.htm "adapted from"]
comment: Starts at day 1 post-fertilization, beginning of the first week.
is_a: HsapDv:0000000 ! human life cycle stage
relationship: part_of HsapDv:0000002 ! embryonic human stage
property_value: start_dpf "0.0" xsd:float
xref: XUO:0000130
xref: EHDAA2:CS01 ! CS01
synonym: "CS01" EXACT [EHDAA2:CS01]

If you want access to the hsapdv ontology to contribute you'd be welcome.
