After importing TextGrids, it appears to be attractive to make levels with label links out of temporally parallel tiers in praat. This is currently not a trivial undertaking.
It should however be feasable to make a wizard which can do this considering the following example:
A collection of Textgrids contains the tiers word and meta (word being orthographic and meta being some other information)
After conversion, for both tiers a labelfile will be present.
In the Template, word is a level with a labfile extension ".word", and meta is a labellink (without a labfile, of course) and we make a path statement for ".meta".
In the wizard we specify "word" as our "main" level and "meta" as the to be imported label link. Given that .word and .meta files have the same number of segments with identical times, the .meta labels can be inserted on the label link. Should someone use files with different time information, the wizard skip the utterance with loud screams of horror.
