  a nara:FileFormat ;
  dcterms:description "VisiCalc, derived from \"visible calculator,\" was a spreadsheet program for personal computing with a user-friendly interface. The native file format consisted of commands and data elements and loading a file would pipe the data into the input stream of the software. VisiCalc could also save files in Data Interchange Format for data exchange with other programs and platforms. VisiCalc was released in 1979 and lost popularity with the 1983 release of Lotus 1-2-3. Lotus purchased VisiCalc in 1985 and ceased selling the software; VisiCalc is considered obsolete and there is limited support for the file format. At this time, further research is required by NARA on processing VisiCalc files." ;
