Act/React (aka Sources/Receptrons):

I know very little about that.

Although you can add Sources/Receptrons under Object properties in DromEd, they are really
links. Unfortunately, each source creates two links:

arSrc contains the link ID of the link which contains the description (aka the real data)
arSrcDesc contains a link from the object to the stim (bugpoke etc) and all the source data.

Since this are closely related links, I will need something like 

Act/React->Source 

as object property, which is then created as the proper links. Unfort. this means reading
in the links must create the property from the link, so that writing out works, too.

Or I make a simple addSource and addReceptron routine, which just adds the two links. Wont
work now, since the link ID going into arSrc is not yet known (created when encoding the
links). So the arSrc link has to be created artificially. I think I stick with a normal
link, which will magically cause the other arSrc to be created.

Receptrons I dont know about, they seem to generate only one link, which is better
to handle.

arScale is a normal object property, though.

Stims are normal archetypes and can be created via

$stim = $gf->addArchetype("Stim","MyStim");
