Open the CIPO recordAbstract From the Canadian patent
A data base system (100) handles nested relational data model (NRDM) data. A metadata mapper (104) converts DTD w/hierarchical structures (102) to NRDM schema that are then stored in schema storage (106). A document (110) is passed to an importer (112), then to a transformation engine (114) and an exporter (116) to result in a document in a new format (118). Because the transformation engine (114) operates on NRDM structures the transformations , can be expressed as a declarative specification thus simplifying the process , of transforming complex data. Exporter (116) exports the data in a suitable form such as XML documents, relational tables or flat files.

Why it's free to use
- Filed February 12, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 12, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 12, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
