Re: Import and export function of SPDX
RUFFIN MICHEL
Well, today we solve more or less this issue by requesting the URL where the FOSs can be downloaded, so URL + name + version number determine the FOSS used. It is not perfect but I never manage a good solution to identify uniquely an open source.

Show quoted text
Even the URL is not enough, when our foss evaluators received a URL to study a FOSS, they have first to check that it is the good one. For instance people are providing the URL on Sourceforge or on a mirror site, while this is not the home page for the software. So our internal recommendation is to use the home page of the copyright owner whenever possible. Not that the URL and version number are the only mandatory fields in our database michel Michel.Ruffin@..., PhD Software Coordination Manager, Bell Labs, Corporate CTO Dpt Distinguished Member of Technical Staff Tel +33 (0) 6 75 25 21 94 Alcatel-Lucent International, Centre de Villarceaux Route De Villejust, 91620 Nozay, France -----Message d'origine-----

What we request is the name of FOSS, the name of the license if it is OSI compliant, or a copy of the license if it is not, the nature of the FOSS: is it a library, a standalone software, an interpreter, ... in order to determine if there is some potential contamination as with GPL.

Hi Michel,
Thanks for contributing details of your SPDX requirements to the mailing list! Apologies for lack of direct reaction to earlier postings, but as you note some of the existing use cases hopefully capture your needs.
I've attached your document to the following use case http://spdx.org/wiki/provide-sufficient-data-allow-consumer-comply-licenses-redistribution
which may be the best fit.
Regarding the desire to produce SPDX documents from legacy data in spite of being able to populate all mandatory fields, there is also a use case
which can be elaborated on.
Best Regards,

1) getting information from our suppliers on FOSS included in their products in order to respect license obligations and to provide this to our customers 2) automate the work of ALU for accepting this FOSS in our products 3) being able to provide the same information to our customers. I think it is covered by actual use cases, if not I can do a new one. Now I would like to attract your attention on a document that I sent few months ago to this mailing list and also to the FSF legal network group. Which are the clauses that we put in the contracts with our suppliers and their rationnal. The goal is to standardize these clauses and I receive no feedback from anybody on this. This should illustrate the use case. And I understand that I should use the FSF legal network to discuss this. But I am very surprised that there is no reaction/interest in this. It has been a huge ALU effort to shape these conditions in order to reach acceptance to these conditions by most companies.

Re: Import and export function of SPDX
RUFFIN MICHEL
No ALU has a DB with 5000 entries for open source maintained since 2002 describing IPR issues. Since 2007 we are requesting from all our suppliers the list of FOSS coming with their products with license, URL of origin, etc. Then one of our 200 FOSS evaluators look at this list compares it to what we have in our database to see if we can accept it or not. He/She enters in the DB the missing entries, … (and I can tell you that this is useful because on nearly 2 contracts on 3 with our suppliers, we find issues that need mitigation). The SPDX standard should allow us to automate partly this process. And our customers are now starting to ask us similar information.
These 2 fields are not relevant in this context to my knowledge. So if these fields are mandatory and we implement an export function, we will generate files that would not be compliant to the standard and then it might be worthless. For the import function we can ignore them I guess.
If there is a good reason for keeping these fields mandatory ALU will try to align its DB on it, but it would be a huge work. But if there is no good reason we ask to make them optional.
We are currently in the process of revisiting all our entries in the database to increase consistency and remove confidential information in order to be able to provide the content of our database to some external partner companies such as Blackduck (and there are others). The goal is to increase the quality and completeness of their database (we have 200 FOSS experts feeding our DB for 5000 entries, Blackduck has a DB of around 500 000 entries, Antelink has a DB of 1 000 000 entries, I do not know for Palamida, Protecode and NextB but it should be similar in range…). This should profit to us by providing better identification with Blackduck tool for instance. I have the long term intention to open source our database in order to share the manpower on this activity, to improve quality of information, to encourage FOSS contributors to control the correctness of information, and to raise awareness on FOSS IP issues (to decrease complexity). For instance our lawyers have done the Plan9 public license, the Lucent Public license (Both OSI certified) the Alcatel-Lucent public license. But we have decided now when contributing to open source to use more standard licenses such as MIT, BSD, Apache2 or GNU family to reduce complexity.

See bellow details

There are two fields that are mandatory in SPDX but have no equivalent in the Alcatel-Lucent FOSS database.
These fields are:
4.3 Package File Name 4.3.1 Purpose: Provide the actual file name of the package. This may include the packaging and compression methods used as part of the file name. 4.3.2 Intent: Here, the actual file name of the compressed file containing the package is a significant technical element that needs to be included with each package identification information. 4.3.3 Cardinality: Mandatory, one.
4.7 Package Verification Code 4.7.1 Purpose: This field provides an independently reproducible mechanism identifying specific contents of a package based on the actual files (except the SPDX file itself, if it is included in the package) that make up each package and that correlates to the data in this SPDX file. This identifier enables a recipient to determine if any file in the original package (that the analysis was done on) has been changed and permits inclusion of an SPDX file as part of a package. 4.7.2 Intent: Providing a unique identifier based on the files inside each package, eliminates confusion over which version or modification of a specific package the SPDX file refers to. The SPDX file can be embedded within the package without altering the identifier. 4.7.3 Cardinality: Mandatory, one.

For example, if i receive an SPDX file w/o a packageVerificationCode, i might decide i need to do my own analysis of the package i am using because i cannot verify that is exactly the one described by the SPDX file. Fortunately, the licensing of software packages rarely change dramatically between versions so i could use the untrusted SPDX data as a starting point. Such a head start would be likely to save a great deal of time and effort. This would be about the same process needed if i received an SPDX file with a packageVerificationCode that did not match my package. Peter PS: This is obviously a forward looking discussion. These fields are mandatory in 1.0, and will be in 1.1, so they need to be in SPDX files produced under those version. However, for 2.0 i think we could greatly encourage adoption by relaxing some of these constraints from "must have" to "should have".

If this is a producer use case where the SPDX is included with a set of files distributed, then the archive file would be the archive file produced and the verification code could be calculated from the files included in the archive. If this is an intermediate use case where existing packages are being documented as SPDX files, I could see where it is more challenging to obtain the archive file and verification code from the original package unless the original package included an SPDX file or the original archive file was maintained.

Import and export function of SPDX
RUFFIN MICHEL
Dear all
As you probably noticed Alcatel-Lucent is trying to implement the SPDX standard.
We have an internal database on FOSS IP issues that has been created in 2002. and we are trying to implement an import/export function in SPDX standard.
We have an issue with 2 fields that do not exist in our database.: the name of the archive file and the checksum. In the SPDX standard they are mandatory and I do not see why would it be possibly to make them optional?
See bellow details
Michel
There are two fields that are mandatory in SPDX but have no equivalent in the
Alcatel-Lucent FOSS database.
These fields are:
4.3 Package File Name
4.3.1 Purpose: Provide the actual file name of the package. This may include the
packaging and compression methods used as part of the file name.
4.3.2 Intent: Here, the actual file name of the compressed file containing the
package is a significant technical element that needs to be included with each
package identification information.
4.3.3 Cardinality: Mandatory, one.
4.7 Package Verification Code
4.7.1 Purpose: This field provides an independently reproducible mechanism
identifying specific contents of a package based on the actual files (except the
SPDX file itself, if it is included in the package) that make up each package
and that correlates to the data in this SPDX file. This identifier enables a
recipient to determine if any file in the original package (that the analysis
was done on) has been changed and permits inclusion of an SPDX file as part of a
package.
4.7.2 Intent: Providing a unique identifier based on the files inside each
package, eliminates confusion over which version or modification of a specific
package the SPDX file refers to. The SPDX file can be embedded within the
package without altering the identifier.
4.7.3 Cardinality: Mandatory, one.

Re: Problem with PackageSourceInfo

Hi Marc-Etienne,

Thanks for catching these. The property name is rdfs:comment for Review. I went ahead and submitted bug 1046 to fix the spec. For 1.1, there is also a web page with the rdf terms at http://spdx.org/system/files/terms.html I went through looking for inconsistencies between the terms and the spec, but missed this one.

Problem with PackageSourceInfo
Marc-Etienne Vargenau
Hello,
In the SPDX 1.0 and spdx-1.1-rc20120403.pdf I read: 7.3.6 RDF: property spdx:comment in class spdx:Review Example: <Review> <rdfs:comment> All of the licenses seen in the file, are matching what was seen during manual inspection. There are some terms that can influence the concluded license, and some alternatives may be possible, but the conluded license is one of the options. </rdfs:comment> </Review> What is correct: "spdx:comment" or "<rdfs:comment>"?

Problem with PackageSourceInfo
Marc-Etienne Vargenau
Hello,
In the SPDX 1.0 and spdx-1.1-rc20120403.pdf I read: 4.9.4 Data Format: free form text that can span multiple lines. In tag format this is delimited by <text> .. </text>. 4.9.5 Tag: “PackageSourceInfo:” Example: PackageSourceInfo: uses glibc-2_11-branch from git://sourceware.org/git/glibc.git. What is wrong: the Data Format or the Example?
