MetaData

• NODE PROPERTIES:

▸ Hash (String); Cardinality ZeroOrOne (optional); This property contains a hash value in the form of a string. Hashes can be used to summarize data, e.g., to summarize the contents of source files or sub graphs. Such summaries are useful to determine whether code has already been analyzed in incremental analysis pipelines. This property is optional to allow its calculation to be deferred or skipped if the hash is not needed.

▸ Language (String); Cardinality one (mandatory with default value <empty>); This field indicates which CPG language frontend generated the CPG. Frontend developers may freely choose a value that describes their frontend so long as it is not used by an existing frontend. Reserved values are to date: C, LLVM, GHIDRA, PHP.

▸ Overlays (String); Cardinality List (many); The field contains the names of the overlays applied to this CPG, in order of their application. Names are free-form strings, that is, this specification does not dictate them but rather requires tool producers and consumers to communicate them between each other.

▸ Root (String); Cardinality one (mandatory with default value <empty>); The path to the root directory of the source/binary this CPG is generated from.

▸ Version (String); Cardinality one (mandatory with default value <empty>); A version, given as a string. Used, for example, in the META_DATA node to indicate which version of the CPG spec this CPG conforms to
