Provide URI/IRI for Morphir IR Nodes and types (i.e. such as Name and Path)

## Feature Request

Provide an [IRI](https://www.ietf.org/rfc/rfc3987.txt) for each Morphir IR Node

### Description of Problem:

It will be simpler to attribute/annotate the Morphir IR in a meaningful way if we encode the attributes in a manner consistent with [RDF](https://www.w3.org/TR/rdf11-concepts/) we should provide an URI which describes each morphir SDK type that is rooted at: https://morphir.finos.org/shemas/ir.

### Potential Solutions:

We should provide these URIs/IRIs in both documentation and code form.

Start by locating the Morphir IR node and type definitions and reviewing the existing documentation. Define how each node receives an IRI rooted at the requested Morphir schema URI, then provide the URIs in both code and documentation. Done means all relevant IR nodes and types have consistent documented and programmatic URIs.
