If you want to publish your applications on Ovi Store for Maemo 5, you have to fulfill certain criteria for the package to be accepted. The technical ones are listed in the document Maemo™ 5 Applications: Ovi Store Entry Requirements. Here are some problematic entries that were not clear to me in the beginning (coming from Extras QA and a Debian-based background):
- The file must be named myapplication_1_0_1.deb (for an application that is called "myapplication"). Interesting factoid: The version number must include three digits (one can interpret that as "no less and no more"). That's different from the Debian standard naming of myapplication_X_armel.deb (where "X" can be any format version number, and "armel" specifies the target architecture). So if you have packaged your application, make sure to rename the file after upload.
- The relation of the file size of /opt compared to the files in /usr must be greater than 1:80. Here's an example from That Rabbit Game: /usr contains two files: The icon (7kB) and the .desktop file (128b) and /opt contains one file: The binary (658kB). However, the difference between these two is not a factor of over 80 when compared with "du -sh" (depending on the filesystem settings).
With that said the structure of the testing criteria in that document is very clear and (apart from some problems with the detailed specs), everything is understandable, well thought-out and can be tested by following the instructions in the document. Some of these could be use to "formalize" the Extras-Testing QA checklist here on Maemo.org or at least provide an easy-to-follow guide for carrying out the basic tests.
