The metainformation is added when you create / edit the schema with the Query Designer. It is not required for running the schema and is skipped when the schema is created manually, for example:
#Open Reading Frame surrounded by repeat units query ORF-Repeats { Repeat { type: repeats; min-length: 10; } ORF { type: orf; } Repeat.left--ORF.unit { type: distance; distance_type: end-to-start; min: 0; max: 5000; } ORF.unit--Repeat.right { type: distance; distance_type: end-to-start; min: 0; max: 5000; } }
