Our SVG mimerule don't have a sniff rule, which make text/html rule wins over if the SVG have a DOCTYPE tag.

Adding a SNIFF_RULE to image/svg+xml checking that an "<SVG" open tag is present in the first 1024 bytes for example should fix this.

I don't understand why it may be identified as a plain text file though: if the SVG file has an .svg[sz] extension at least, the current image/svg+xml MIME definition should wins.

Could you attach to this ticket samples SVG files that trigger either text/html or text/plain mis-identification? Thanks.

Personally I don't think that file extensions work. Recognizer always use sniff rules. Mayble I am wrong.

Then will file be recognized by extension in theory?

Player.svg is identified as text/html because text/html SNIFF_RULE find a <!-- in the first 64 bytes and, unfortunatly, image/svg+xml don't have SNIFF_RULE saying if there is a <svg in the first ~512 bytes it's certainly a SVG file, not an html file at a 40% probability ;-)

And calendar.svg ends as text/plain maybe, indeed, the file extension is not working yet. Anyway, let's add this string attribute to your mime_beos/image/svg+xml:

attribute name:

META:SNIFF_RULE

type:

String

value:

0.60 [0:512] ( -i "<SVG" | "<!DOCTYPE SVG")

That will translate in append these lines to src/data/mime_beos/image/svg+xml:

+ resource(4, "META:SNIFF_RULE") #'CSTR' array {
+	"0.60  [0:512]( -i \"<SVG\" | \"<!DOCTYPE SVG\")"
+ };

My bad, should be:

0.60 [0:511] ( -i "<SVG" | "<!DOCTYPE SVG" )

And considering that we don't currently SVN image translator, maybe it's better too to set Web+ as preferred application for SVG image:

+ resource(4, "META:SNIFF_RULE") #'CSTR' array {
+	"0.60 [0:511] ( -i \"<SVG\" | \"<!DOCTYPE SVG\" )"
+ };
+
+resource(5, "META:PREF_APP") #'MSIG' "application/x-vnd.Haiku-WebPositive";
