Even though we frequently tout that we are not just a file indexer, we need to index the files properly. Contents 1 File Indexing solutions 1.1 Strigi 1.2 Roll our own? 2 File Formats 2.1 Images 2.2 Videos 2.3 Audio 2.4 Documents File Indexing solutions Strigi KDE 4.9, currently uses libstreamanalyzer to index the files. Current problems with strigi - Difficult to contribute to No documentation Un-maintained Does not reuse libraries Lists the current status of indexing different files. Roll our own? File Formats We list down all the different file formats, and which all are supported by the different file indexing solutions. Images JPEG - Use exiv - strigi also uses exiv - currently broken PNG - Strigi rolls its own - detects the application name, color depth and interlace mode as well GIF - there isn't much metadata EXIF TIFF BMP SVG - Strigi stores them as plain text We just just use exiv2 and cover almost everything. Plus the code would be super simple. Videos Audio MP3 Documents doc docx odf pdfs epub mobi spreadsheet formats Presentation Formats lyx tex cbz - Comic books Archives tar gzip whatever ..
