Currently we do not do anything with what we think are notices. Notices are detected as text files that have specific names. I think that we should run them through the standard processing to see if they have text for other licenses in them. This is important for ASF Notice files where we are supposed to list 3rd party licenses that require copyright notices to be included.
In addition items tagged as Notices should be run through the SPDX license detection software. I don't want to do this for all standard files because the license detection utilises regular expressions and will slow down processing. However, we expect to find license declarations in some notice tagged files, for example the ASF "LICENSE" file. This will involve the inclusion of SPDX libraries, but will give us a big boost in the ability to detect 3rd party licenses. Thoughts? Claude
