An importer/exporter of Moose Model using the parquet file format
# MooseParquet MooseParquet exports and imports Moose models using Apache Parquet files. It provides a small set of exporters and importers to persist Moose entities, their scalar properties, and their relationships in a tabular graph-oriented format. ## Installation Load MooseParquet with Metacello: ```smalltalk Metacello new baseline: 'MooseParquet'; repository: 'github://Evref-BL/MooseParquet:main/src'; load. ``` ## Example Usage: Export Export a Moose model to Parquet files: ```smalltalk exporter := MooseParquetExporter new. exporter model: MooseModel root anyOne. exporter export. ``` The exporter writes the following files: - `entities.parquet` - `entities_properties.parquet` - `relationships.parquet` These files contain the model entities, their exported scalar properties, and the relationships between entities. ## Example Usage: Import Import the generated Parquet files into a Moose model: ```smalltalk modelJava := FamixJavaModel new. importer := MooseParquetImporter new. importer model: modelJava. importer importEntities. importer importEntitiesProperties. importer importEntitiesRelationships ``` The import process should be run in this order: entities first, then scalar properties, then relationships. This ensures that every relationship can be resolved against entities already present in the target model.
