George wrote about backward compatibility; and Steve about moving on. But it does seem to me that Braille producers who archive files have an interest in divining the future, as regards the uses of those archives over time. Would there be best practice principles any of you are prepared to recommend? For example, George, do you actually believe that we will, in due course, be archiving XML only? And what then about the older Braille files? Are the people at Duxbury Systems thinking about these things, or am I the only one who needlessly worries about archiving? Legacy data is a problem. I can see the issues as Duxbury rolls over to new versions, there may come a time when you need to dig out your old copy of duxbury to re-emboss the file you saved. One thing that might help, is to store, with the file, some information about the file, the version of duxbury it was created on, as well as the document information, e.g. title, copyright, originator, date of transcription. With this level of metadata, it will be easier to recall older documents for reproduction. Dave D mentioned storing Word files. I would be reluctant to advise that, since word is guaranteed to change over time; and anyway, who wants their information locked up in a proprietary format without good reason? That's the advantage of archiving in a format which should have a longer life-span and is application neutral, such as XML. regards DaveP. ** snip here ** -- DISCLAIMER: NOTICE: The information contained in this email and any attachments is confidential and may be privileged.
