As a software developer working with Lotus Notes, I would like to formally request the release of documentation for the NSF file format. Lotus Notes has a huge install base, and your customers have invested a lot of trust in your product, storing vital information within Notes databases.
If it was documented, we could write our own tools to work directly against the data, removing some of the burden from the Lotus Notes development team to support enhancements to the published APIs.
One of your primary competitors -- Microsoft Outlook/Exchange -- has recently taken a bold step forward by releasing the documentation of their equivalent PST format. Much like Lotus Notes, and the NSF format, the only historical way of accessing data in a PST was via limited proprietary APIs.
Releasing the documentation for the PST format was a huge gesture of understanding from Microsoft and shows a lot of concern for their customer base, and those who service and support their customers. It's those kinds of display of concern that create customer loyalty and encourage users to continue using their products.
Please step up to the plate and show your customers that you care about them as a company. Please provide documentation for the structure of your data files.
For reference, here's the Microsoft announcement of their intention to release the PST format specification.
