Simple autotagging

The script assign keywords to documents name based in database metadata values present into document content. Database metadata:

-- DOCS TYPE
DELETE FROM OKM_DB_METADATA_TYPE WHERE DMT_TABLE='doc_type';
INSERT INTO OKM_DB_METADATA_TYPE (DMT_TABLE, DMT_REAL_CoLUMN, DMT_TYPE, DMT_VIRTUAL_CoLUMN) VALUES ('doc_type', 'col00', 'text', 'dt_id');
INSERT INTO OKM_DB_METADATA_TYPE (DMT_TABLE, DMT_REAL_CoLUMN, DMT_TYPE, DMT_VIRTUAL_CoLUMN) VALUES ('doc_type', 'col01', 'text', 'dt_description');
