MIME types

The application supports several document MIME types. Every MIME type has one or several file extensions which are used to match the uploaded document’s MIME type.

Caution

Based on the MIME type associated with the uploaded document, the application chooses the associated text extractor. The text extractor works only for a few MIME types; it can easily be extended.

For example, if you upload a “sample.doc”, its detected MIME type is “application/msword” because its extension is “.doc”. In this case, the text extractor class is “com.openkm.extractor.MsWordTextExtractor”.

The detected document MIME type is also used to display an icon which represents the type of document. You can change this icon if you like.

There is a list of common document MIME types already registered in OpenKM.

Caution

If you upload a document which MIME type is not in the list, it will be detected as “application/octet-stream”.
