class swh.indexer.metadata_dictionary.maven.MavenMapping(log_suffix='')[source]#

Bases: XmlMapping, SingleFileIntrinsicMapping

dedicated class for Maven (pom.xml) mapping and translation

name = 'maven'#

filename: bytes | Pattern[bytes] = b'pom.xml'#

string_fields: List[str] = ['name', 'version', 'description', 'email']#: List of fields that are simple strings, and don’t need any normalization.

extra_translation(graph: Graph, root, d)[source]#: Called at the end of the translation process, and may add arbitrary triples to graph based on the input dictionary (passed as d).
