SgtChaireBourne writes "NLnet, a Dutch foundation for an open information society, has publicly called for Microsoft to release its deprecated formats into the public domain. The maker of Office has made large efforts during the last year to move against the OpenDocument Format (ISO/IEC 26300). These efforts have been producing a lot of commentary regarding the amount of data bound up in the Redmond-based company's proprietary specifications. It's a nasty situation to end up with files that cannot be read because the sole vendor with the documentation for the files has withdrawn permission. ODF is the way forward, or a step forward at the least, with new documents. But for the old documents in the legacy formats, they cannot be read without supporting software and that support requires full access to the specifications."
