A DMN model as data: the Definitions of DMN 1.6 (clause 6.3.2), read from an XML document by Dmn.Reader.
The structs follow the metamodel of the specification, and each field is the attribute or the association of the same name in
snake_case. They hold what the document says and nothing is decided yet: no name is resolved, no FEEL is read, no
reference is followed. That is Dmn.Compiler. A struct that came from an element has its id and the line of the document.
- the DRG elements are in lists by kind, each in document order:
decisions,input_data,business_knowledge_models,decision_services,knowledge_sources; - the expressions of a decision are the structs of
Dmn.Model.ExpressionsandDmn.Model.DecisionTable; - a reference (
href="#id",href="namespace#id") is aDmn.Model.Reference.t/0.
| Field | Is |
|---|---|
version | :dmn_1_1 to :dmn_1_6, from the namespace of the document |
namespace | the namespace of the definitions, which the elements of the model are in for the other models |
expression_language, type_language | the URIs of the defaults of the model (nil for FEEL) |
imports | the Dmn.Model.Imports |
item_definitions | the Dmn.Model.ItemDefinitions |
base_uri | where the document was read from, which a relative locationURI of its imports is resolved against (DMN 1.6, 13.3.2; RFC 3986); nil if that is not known. Not in the document: Dmn.load/2 takes it as an option, and Dmn.Imports sets it for the models it reads, from what the resolver says |
sha256 | the SHA-256 of the bytes the model was loaded from (lowercase hex, digest/1), or nil for a model that was not loaded from bytes. Not in the document: Dmn.load/2 sets it, and it is what Dmn.Imports tells the first model by when a model it imports names the namespace of the first one |
Summary
Functions
The SHA-256 of the bytes of a document, in lowercase hex: how a model is told from another one with the same namespace.
The DRG elements of every kind, in the order of the kinds above and the document within a kind.
