in reply to Creating Metadata from Text File
You mention the "limit i think for an oracle varchar2 table is at least 5000 bytes"; I think you mean that a single Varchar2 column can hold about 4000 1 byte characters (less if using multibyte).
Does that mean you are going to store the entire word list you are generating in a single Oracle column on a table? That could be a very large table... and searching against a freeform column (which is why I assume you are putting this data into an Oracle table) is *extemely* slow.
What is the format for your metadata, ultimately? Are you attempting to encode RDF or RDFS or something else?
