Thank you for the suggestion. I think that it is reasonable to include in glpk some api routines to read and write lp/mip instances as well as basic/interior-point/mip solution from/to a text file in a more convenient format, which would include row/column names. A DIMACS-like format seems to me most suitable, because it allows easily using standard text utilities like sed, gawk, etc. Using XML seems to me much more tricky and much less convenient for processing out of glpk.
