Provenance entity constraints

[shirey]

The working set of constraints for provenance hierarchy (this needs to be reviewed by domain experts) are given by the following allowed direct ancestor links:

   Source-->organ
   organ-->block
   block-->section
   section-->suspension
   block-->block
   block-->suspension
   section-->Dataset
   suspension-->Dataset
   Dataset-->Dataset
   block-->Dataset where type of Dataset must be Lightsheet (additional datatypes may be added in future)
   organ-->suspension where type of organ must by blood

@shirey Can a Dataset have another Dataset as an ancestor?

[shirey]

@maxsibilla Yes, absolutely-- I'll add Dataset --> Dataset above..

[shirey]

We will allow block-->Dataset because assays like Lightsheet work directly on a block.

Refactored duplicate keys

Source-->[organ] organ-->[block] block-->[section, block, suspension, Dataset] section-->[suspension, Dataset] suspension-->[Dataset] Dataset-->[Dataset]

After further conversations last week, I added the following to the constraints above-

• On the block-->Dataset constraint the type of Dataset must be Lightsheet and additional data types to constrain against may be added in future
• added new constraint organ-->suspension where type of organ must by blood
