5. Difficulties encountered:
1. A lot of manual work. Many of data are not stored in the database what creates some errors and inconsistency between the sets of CDI and odv files.
2. Some problems with units selection.
NEMO has been used to crate a header for odv files using vocabulary. We used simple unit mmol/dm3 while found difficulties with selection of the proper ones from vocabulary.
3. The change of the vocabulary required all odv correction.
