@David, spot on – this is precisely what we do when submitting a query to NIST 
NVD, we strip everything, except the filename from the filename content.

 

Thanks,

Subject: Re: [spdx-tech] FileNames in SPDX File item

 

More completely, 
https://spdx.github.io/spdx-spec/v2.3/file-information/#81-file-name-field says:

Identify the full path and filename that corresponds to the file information in 
this section.
Format: A relative filename with the root of the package archive or directory.
In general, every filename is preceded with a ./, see 
http://www.ietf.org/rfc/rfc3986.txt for syntax.

 

So the syntax is a path "relative to the package archive or directory", not 
just a bare filename with a "./" prefix.  Unfortunately the package name 
("Provide the actual file name of the package, or path of the directory being 
treated as a package.") is optional but file name is required, which is 
confusing.

Fortunately this corresponds to the SPDX 3 decision to NOT support 
downloadLocation property for File; i.e. files only have meaning in the context 
of packages.  Presumably the same "name" requirements copy directly from 2.3 to 
3.0.

Question: Since 2.3 File name is required but Package name is optional -- is 
there any situation where a relative file name is meaningful without a base?  
If not, is Package name optional a bug / mistake?

@Dick: Given a path, applications can submit just the filename portion in 
queries.

Anthony,

 

Based on our experiences, the presence of any path information creates problems 
when searching NIST NVD that could result in false negatives, during a risk 
assessment. We strip all path info from the filename before submitting a NIST 
NVD vulnerability search request.

Subject: [spdx-tech] FileNames in SPDX File item

 

Colleagues

A couple of questions on files specified in a SPDX File item.

According to the SPDX spec, the filename for a SPDX file is a relative filename 
(prefixed by ./). - see 
https://spdx.github.io/spdx-spec/v2.3/file-information/#81-file-name-field. 
However providing a relative path doesn't help identify the source of the 
actual location of the file. Where should the absolute path be specified (I 
think we just need the root)? I have thought about putting the file path as a 
FileComment but that is probably abusing the purpose of this field.

Are we assuming that ALL files in SBOM are within the same file tree? I have 
assumed that if I encounter a link in the tree, I would use the actual file 
location rather than it's link but this is likely to be in another part of the 
directory tree. If this is the case, would that mean we would have to create a 
sep[arate SBOM for files in a different part of the directory tree?

Regards

Anthony
