ST1 derives from ST2 means ST1 is more specific than ST2. -If a service implements ST1, it also implements ST2, but not the other way round. - -For instance, KoDocument derives from KParts/ReadWritePart, which derives from KParts/ReadOnlyPart, -so KWord's part (which implements KoDocument) can be used as a readonly viewer for KWord files -in Konqueror (which looks for a KParts/ReadOnlyPart). - -Mimetype "inheritance" -====================== -We need a mechanism to also say that "text/xml is a special case of text/plain", -or "text/docbook is a kind of text/sgml", or "application/x-smb-workgroup is a kind -of inode/directory", etc. See below. - -Why mimetype "inheritance" doesn't use X-TDE-Derived -==================================================== -The confusing thing is that we said "a mimetype is a servicetype". But that's not exactly correct. -As Waldo noted, "the ability to open a mimetype" is what's a servicetype. -So if text/xml said X-TDE-Derived=text/plain (i.e. ST1=text/xml, ST2=text/plain), -then an application opening text/xml (ST1) could also open text/plain (ST2) - which is not necessarily true. - -We want the other way round: to be able to open special kinds of text/plain in a plain text editor. -This is what X-TDE-IsAlso was introduced for. X-TDE-IsAlso kind of "works the other way" than X-TDE-Derived. -If M1 is a special kind of M2 (mimetypes), then "the ability to open M2" derives from "the ability to open M1" -So we say in text/xml: X-TDE-IsAlso=text/plain, and applications that can open text/plain can also open text/xml. - -Pattern Accuracy -====================== -In some cases of inheritance several mimetypes shares the same extension (with the primary case being Ogg Multimedia files). -This has been solved sofar by matching the extension to most generic mimetype. To indicate that the mimetype can be refined further, the flag X-TDE-PatternsAccuracy can be set. The value to X-TDE-PatternsAccuracy is a number between 0-100, with 100 being the default if not set. Any values below 100 is interpreted as the possibility of further mimetype refinement. |
