=Proposed 2021 Projects=
  
=SPDX Workgroup Tooling Projects=
+
Mentors:  please fill out the following template for any projects you wish to propose.  
These projects are aimed at contributing to the SPDX tools to help reduce the effort to create SPDX and increase the accuracy of the SPDX documents.
+
  
==Enhanced Workflow for Online License Request==
+
=== Project Name ===
Update the SPDX Online Tools license submit feature to support the following workflow:
+
add overview of project here
* License submit can be initiated directly from the UI or through an external application (e.g. the [https://github.com/spdx/spdx-license-diff SPDX License Diff browser plugin]) using a documented API
+
====Skills Needed====
* License text is compared to the currently approved license list
+
what skills should the student have to do the coding exercises
** If matched, the SPDX ID is returned and the user is informed that the license already exists
+
====Background Information====
* License is compared to all submitted yet not approved licenses
+
context for the project and references to be studied
** If matched, the user is informed the license is already submitted and is provided a link to the [https://github.com/spdx/license-list-XML/issues License List XML issue]
+
====Available Mentors====
* License is compared to all submitted and rejected licenses
+
list individuals who are willing to mentor and provide information about the project proposal.  
** If a match is found, the user is provided a link to the [https://github.com/spdx/license-list-XML/issues License List XML issue]
+
 
* License is compared to the existing license list using an algorithm which finds close matches (SPDX License Diff is an example)
+
(The projects from 2019 can be found on the [https://summerofcode.withgoogle.com/organizations/4532099550281728/#5727887162867712 2019 Google Summer of Code projects page for SPDX] ).
** If an existing license is close, a diff view will show the word differences
+
 
** The user is presented with a choice of adding an issue for the nearly matching license stating that the license should match
+
==SPDX Workgroup Tooling Projects==
*** If the user chooses to add the issue, the license text will be added to the issue requesting a change to the license XML to allow the match
+
These projects are aimed at contributing to the SPDX tools to help reduce the effort to create SPDX documents and increase the accuracy of them.
*** We could also implement suggested XML markup (e.g. alt or optional text) to make the licenses match - NOTE: This may be a technically challenging feature to implement
+
 
* If the user wants to submit a new license request, the information is captured and processed by the SPDX legal team through [https://github.com/spdx/license-list-XML GitHub]
+
=== Migrate SPDX Online Tools to DJango3 ===
 +
Migrate the SPDX online tools to later versions of Django and upgrade dependencies (such as Django Social Auth) to later version to support better / more secure authentication to Github.  In addition to migrating to DJango 3, additional issues can be taken on to create a full GSoC project (see the list below).
  
 
====Skills Needed====
 
====Skills Needed====
* Development skills in the Python language
+
* Experience with Python3 programming
* Experience with parser development
+
* Familiar with Django framework
* Experience proposing spec changes
+
* Understanding of Github API's
+
* Experience in XML parsing
+
  
 
====Background Information====
 
====Background Information====
The SPDX legal team uses an online request process for new license requests. This feature was implemented by a GSoC student in 2018Extending the functionality to check for duplicate requests and checking for near matches would greatly improve the efficiency of the license request and approval process.
+
The SPDX Online Tools are currently being migrated to Python3. Several libraries can now be upgraded to more supportable versions including DJangoThere are some known issues with the current version of Django Social Auth which would be resolved by upgrading the versions.  There may be additional libraries which can be upgraded.  There is also an opportunity to improve the structure and unit tests for the online tools if time allows.  See the [https://github.com/spdx/spdx-online-tools/tree/rtgdk_python3 Python3 Branch] of the SPDX online tools for the current state of the Python3 migration.
  
This project would require significant interaction with the users of the tool (the SPDX legal team) and would have some interesting technical challenges in storing and matching text. The optional feature of suggesting XML markup for near matches could involve sophisticated matching techniques to find the appropriate text to include as optional or alternate.
+
Additional tasks and issues can can be included in a project (in priority order):
 +
* Migrate project to python3 and Django3 [https://github.com/spdx/spdx-online-tools/issues/58 issue 50] and [https://github.com/spdx/spdx-online-tools/issues/24 issue 24]
 +
* [https://github.com/spdx/spdx-online-tools/issues/287 Merge app and api code]
 +
* Fix and improve test [https://github.com/spdx/spdx-online-tools/issues/201 issue 201] [https://github.com/spdx/spdx-online-tools/issues/282 issue 282], [https://github.com/spdx/spdx-online-tools/issues/202 issue 202] + others
 +
* [https://github.com/spdx/spdx-online-tools/issues/299 Add a submit via mail functionality to license submittal]
 +
* [https://github.com/spdx/spdx-online-tools/issues/218 Store license diff screenshot in database instead of uploading to github]
 +
* [https://github.com/spdx/spdx-online-tools/issues/157 Improve error message when error received from the Java code]
 +
* [https://github.com/spdx/spdx-online-tools/issues/186 Add a License Diff section to the SPDX Online Tool]
 +
* [https://github.com/spdx/spdx-online-tools/issues/91 API documentation tool]
 +
* API for license namespace
 +
* [https://github.com/spdx/spdx-online-tools/issues/204 Move to Github Apps and improvement for production]

====Background Information====
SPDX currently provides libraries supporting the reading and writing of SPDX document.   
+
RDF/XML is one of the supported formats for SPDX documentsCreating an RDFWriter would create a generally useful facility for Golang and provide a more modular structure for the SPDX Golang tools.
  
A rewrite of the Golang tools for SPDX 2.1 is in process at [https://github.com/swinslow/spdx-go github.com/swinslow/spdx-go], but does not yet support RDF. The libraries should support both RDF/XML import/export as well as tag/value import/export.  The tools should also support newer formats such as JSON and YAML as the SPDX definition for those formats continues to be established.
+
See the [https://github.com/spdx/tools-golang SPDX Golang tools repo] and the [https://github.com/spdx/gordf gordf library] for more details on the current implementations.

==SPDX Specification Projects==
 +
The following projects contribute directly to the creation or validation of the SPDX specification.
 +
 
 +
=== Generate a JSON Representation of the Specification from Structured Markdown ===
 +
Convert a consistently structured Markdown file into a JSON structure following a well defined schema.  Changes to an existing Markdown file should update the JSON files.  The Markdown will have a well defined structure to allow for translation of the text in Markdown to the properties of the JSON file.  The conversion will also validate that the Markdown follows the required specification.  The conversion would be run as part of a Github action for the SPDX specification.
  
== Port SPDX license expression library to Ruby, JavaScript and Java==
 
The [[https://github.com/nexB/license-expression/]|licens_expressionlibrary]] provides comprehensive support license expression using a boolean engine for Python.
 
The goal of this project is to port and/or package this library for JavaScript, Ruby and Java, considering either code conversion tools, alternative Python implementations (e.g. Jython) or calling Python from another language to bring the same features to these other languages.
 
 
====Skills Needed====
 
====Skills Needed====
* Development skills in Python, Java, Ruby, JavaScript.

 +
* Knowledge of Markdown and JSON syntax
  
 
====Background Information====
 
====Background Information====
See https://github.com/spdx/tools-python/issues/10 and https://github.com/nexB/license-expression/
+
The SPDX tech team works very collaboratively on the specification updates using markdown pages in GitHub as the primary documentation for the specification.  RDF/OWL is used as the primary technical specification for the object model including relationships, cardinality, class structure, and other restrictions.  There is a lot of overlap between the information in the Markdown and the information in the OWL document.  To improve the quality and productivity of the specification work, the SPDX technical team has decided to add tooling for verification of the Markdown and conversion of any common information to the OWL document.  The conversion will be in 2 stages:
 +
* Convert from Markdown to an intermediate JSON format
 +
* Convert from the JSON format to RDF/OWL
 +
 
 +
The specific schema for the JSON format is under development and planned to be available before the start of GSoC.

* Willingness to learn about open source licensing and related technical matters
 +
 +
====Background Information====
 +
Export a ClearlyDefined workspace as a SPDX document:
 +
* user to navigate to https://clearlydefined.io/workspace
 +
* Add one or more components to the workspace through any of the existing means, 
 +
* then click Share,  and then slick SPDX (choice of 2.2 supported output formats).
 +
which would result in an SPDX document is exported containing all of the components that were in the workspace.
 +
Note:  If there is mandatory information required by SPDX that ClearlyDefined does not have we will need to determine how to accommodate that.
 +
 +
To populate a workspace from a SPDX document:
 +
* user to navigate to https://clearlydefined.io/workspace
 +
* drag a SPDX document into the workspace and then all of the components in the SPDX document are added to the workspace.
 +
 +
There are some discrepancies between the content in ClearlyDefined and that SPDX documents, so work would be needed with both communities to figure out: what to do if license information in the SPDX disagrees with what ClearlyDefined has and how to handle pending curations?

Welcome to the 2021 SPDX Google Summer of Code Project Page

See the proposal template if you are interested in submitting a Google Summer of Code proposal.

Should you have questions please do not hesitate to contact one of the mentors directly.



What is SPDX ?

First and foremost we are a community dedicated to solving the issues and problems around Open Source licensing and compliance. The SPDX work group (part of the Linux Foundation) consists of individuals, community members, and representatives from companies, foundations and organizations who use or are considering using the SPDX standard. The work group operates much like a meritocratic, consensus-based community project; that is, anyone with an interest in the project can join the community, contribute to the specification, and participate in the decision-making process. We come from many different backgrounds including open source developers, lawyers, consultants and business professionals, many of who have been involved with license compliance and identification for years.

As part of this effort we have developed a set of collateral that can be used:

Why choose an SPDX Project?

Contributing to one of the SPDX projects below will provide a valuable contribution to developers and/or users of open source software. We believe you will find the projects both technically challenging and rewarding. In essence we believe you will be able to look back one day and I say I was part of that effort.


Getting Involved

Beyond working with your mentor(s) we highly encourage students who select one of these projects to get involved with the SPDX community via our technical working group. Interaction with the technical team is primarily done via its mailing list and on gitter (see resources). There is however a weekly call you could join as well. .

SPDX Workgroup Tooling Projects

These projects are aimed at contributing to the SPDX tools to help reduce the effort to create SPDX documents and increase the accuracy of them.

Migrate SPDX Online Tools to DJango3

Migrate the SPDX online tools to later versions of Django and upgrade dependencies (such as Django Social Auth) to later version to support better / more secure authentication to Github. In addition to migrating to DJango 3, additional issues can be taken on to create a full GSoC project (see the list below).

Skills Needed

  • Experience with Python3 programming
  • Familiar with Django framework

Background Information

The SPDX Online Tools are currently being migrated to Python3. Several libraries can now be upgraded to more supportable versions including DJango. There are some known issues with the current version of Django Social Auth which would be resolved by upgrading the versions. There may be additional libraries which can be upgraded. There is also an opportunity to improve the structure and unit tests for the online tools if time allows. See the Python3 Branch of the SPDX online tools for the current state of the Python3 migration.

Additional tasks and issues can can be included in a project (in priority order):

Migrate Python Tools to Python 3

Migrate the SPDX Python Tools to Python 3 including all unit testing. In addition, additional known issues raised on GitHub may be tackled.

Skills Needed

  • Experience with Python3 programming
  • Knowledge of parsing algorithms

Background Information

The Python tools are command-line tools and a library that implement reading and writing of SPDX files in different formats, as well as converting and validating SPDX files. The current implementation uses Python 2, which is no longer supported. In addition to migration, some additional tasks may be taken on to improve the supportability of the library.

RDF Writer for Golang

Gordf supports writing rdf triples to rdf file. Create an interface that would take in a SPDX document and generate RDF triples out of it. Which will then be consumed by the gordf to generate a RDF/xml file.

Skills Needed

  • Knowledge of RDF
  • Skills in XML parsing
  • Knowledge and experience in Golang

Background Information

RDF/XML is one of the supported formats for SPDX documents. Creating an RDFWriter would create a generally useful facility for Golang and provide a more modular structure for the SPDX Golang tools.

See the SPDX Golang tools repo and the gordf library for more details on the current implementations.

SPDX Specification Projects

The following projects contribute directly to the creation or validation of the SPDX specification.

Generate a JSON Representation of the Specification from Structured Markdown

Convert a consistently structured Markdown file into a JSON structure following a well defined schema. Changes to an existing Markdown file should update the JSON files. The Markdown will have a well defined structure to allow for translation of the text in Markdown to the properties of the JSON file. The conversion will also validate that the Markdown follows the required specification. The conversion would be run as part of a Github action for the SPDX specification.

Skills Needed

  • Skills in writing parsing algorithms (e.g. working with Abstract Syntax Tree)
  • Knowledge and experience in the programming language chosen for the project (e.g. Java, JavaScript, Python)
  • Knowledge of Markdown and JSON syntax

Background Information

The SPDX tech team works very collaboratively on the specification updates using markdown pages in GitHub as the primary documentation for the specification. RDF/OWL is used as the primary technical specification for the object model including relationships, cardinality, class structure, and other restrictions. There is a lot of overlap between the information in the Markdown and the information in the OWL document. To improve the quality and productivity of the specification work, the SPDX technical team has decided to add tooling for verification of the Markdown and conversion of any common information to the OWL document. The conversion will be in 2 stages:

  • Convert from Markdown to an intermediate JSON format
  • Convert from the JSON format to RDF/OWL

The specific schema for the JSON format is under development and planned to be available before the start of GSoC.

Below are some additional resources for this project:

Generate RDF/OWL from from JSON specification format

Convert a set of JSON files into a Web Ontology Language XML document. The JSON file will map to the elements and attributes of the RDF/OWL XML file. The JSON schema will be defined prior to the project start and will be consistent with the "Generate a JSON Representation of the Specification from Structured Markdown" project described above.

Skills Needed

  • Knowledge and experience in the programming language chosen for the project (e.g. Java, JavaScript, Python)
  • Knowledge of RDF/OWL/XML formats
  • Knowledge of JSON parsers

SPDX Specification Views for legal counsels and developers

The proposal is to see if it possible to deduct large SPDX documents into a small subset SPDX document providing a specific reduced "views" on larger data.

Skills Needed

  • Understanding of compliance needs of legal counsels and developers so we can remove friction to adopt SPDX

Background Information

SPDX documents commonly contain 100s, if not 1000s of entries making it hard for a human to make manual corrections or draw conclusions. No scanner can provide 100% complete data human corrections are usual needed. The aim from this proposal is twofold: 1. Enable developers with a "code view" of tool-generated SPDX document close to the code they work on to enable them to make corrections to the SPDX data. For instance amend SPDX package tag values or model package dependencies not detected by used scanner. 2. Provide legal counsels with a "package and limited file view" to enable legal conclusions

ClearlyDefined exporting and importing SPDX documents

The goal of this GSoC project would be to add support in the ClearlyDefined project to export curated data into SPDX 2.2 documents. Once that is accomplished, being able to import SPDX documents into the curated database would be the next step.

Skills Needed

  • Experience with JSON and YAML (XML a plus)
  • Ability to interpret and implement the SPDX specification and related ClearlyDefined community documentation
  • Ability to work with the community in integrating results with other projects
  • Willingness to learn about open source licensing and related technical matters

Background Information

Export a ClearlyDefined workspace as a SPDX document:

  • user to navigate to https://clearlydefined.io/workspace
  • Add one or more components to the workspace through any of the existing means,
  • then click Share, and then slick SPDX (choice of 2.2 supported output formats).

which would result in an SPDX document is exported containing all of the components that were in the workspace. Note: If there is mandatory information required by SPDX that ClearlyDefined does not have we will need to determine how to accommodate that.

To populate a workspace from a SPDX document:

  • user to navigate to https://clearlydefined.io/workspace
  • drag a SPDX document into the workspace and then all of the components in the SPDX document are added to the workspace.

There are some discrepancies between the content in ClearlyDefined and that SPDX documents, so work would be needed with both communities to figure out: what to do if license information in the SPDX disagrees with what ClearlyDefined has and how to handle pending curations?
