Goal: Build semantic web of FOSS and promote SWH in citation and metadata workflows

1. implementation metadata infrastructure/workflow (all tasks are under #Metadata workflow)
  - [x] strategy and design of metadata component [#T715]

  - storage layer (tables and api entry points)
    - [x] content level [#T733]
    - [x] revision level [#T741]
    - [x] origin level [#T737]

  - indexer layer:
    - [x] content indexer [#T715]
    - [x] revision indexer [#T738]
    - [x] origin indexer [#T1231]

  - fetch extrinsic metadata
    - [x] with deposit [#T832] + loader-core [#T852]
    - [ ] when listing [#T833]
    - [ ] when loading [TBD]
    - [ ] from external catalogs (e.g libraries.io) [TBD]
  - [ ] deploy 
  - [ ] document metadata workflow for coders and 'normal' users [TBD]

2. implementation of metadata tools for detection/extraction/translation
  - [x] swh-metadata-traslator to CodeMeta schema
    - [ ] coverage CodeMeta crosswalk table
  - [x] swh-metadata-detector (heuristic for filenames containing metadata) 
  - [ ] CodeMeta generator

3. contacts and communication aka metadating
  - [x] RDA- metadata presentation at 10th RDA plenary
  - [x] Force11 SCIWG- hackathon participation
  - [x] Wikidata for preservation- Pathways for Discovery of Free Software: Libre Planet 2018 submission
  - HAL-CCSD- deposit
        - [x] submit french poster for JSO2018
        - [x] submit english poster for RDA & Liber 2018
        - [x] write blog post [#T769]
        - [x] prepare demo script for FOSDEM- GNU Hello [#T882]
  - [x] Crossminer- define collaboration
  - [ ] CodeMeta- contribute to crosswalk table and discussions
  - [ ] create and keep metadata network ( SPN, TOTEM, Ontosoft, CHM, etc..)
  - [ ] call for contribution to swh-metadata-tools

4. user features:
  - [] view indexed metadata for artifact on web UI (content, revision, origin)
  - [] search over metadata
    - [] Basic search
    - [] Advanced search (on specific terms)

5. Research and specify metadata use cases (not necessarily SWH):
  • scholarly ecosystem and open science
    - [x] Preserve research software (https://www.softwareheritage.org/save-and-reference-research-software/)
    - [x] Credit and attribution (activity report)
    - [x] Reference and identify software artifacts (activity report)
    - [x] Moderate research software (activity report)
    - [] Evaluate research software
  • culture and digital preservation
    - [x] Acquire and Archive legacy software source code (https://www.softwareheritage.org/swhap/)
       - [x] collect
       - [x] curate
       - [x] archive
       - [] present
    - [] Emulate legacy software [Acquire -> Archive (in SWH) -> Retrieve (on EaaSi) -> Use]
    - [] Archive cultural ephemera and context
  • web semantics and linked data
    - [] connect/ link software source code over the WWW
    - [] create the FOSS graph
    - [] use search engines to find software source code
  • free and open source software
    - [] recommendation systems: asses quality of software components and similarity between components
    - [] provenance of software artifacts  
    - [] determine legality of usage, modification and redistribution 

6. Document SWH user stories and provide detailed guide(s):
Existing user stories:
  - [] deposit software with HAL
    - [x] text (on HAL)
    - [] video
  - [] save code now (research software)
    - [x] text
    - [] video
  - [] swhap
    - [x] text
    - [] video

In roadmap user stories:
  - [] retrieve metadata for citation 
    - [] text
    - [] video
  - [] search SWH archive (url and metadata)
    - [] text
    - [] video
  - [] View software artifact and metadata
    - [] text
    - [] video
  - [] Fetch software artifact and metadata (API)
    - [] text
    - [] video
  - [] Create codemeta.json with CodeMeta generator (after publishing tool on GitHub)
    - [] text
    - [] video

Wish-list user stories:
  - [] retrieve BibTex for an artifact (WebApp and API) [is it really possible?]
  - [] retrieve codemeta.json export for a revision or origin  [is it really possible?]
  - [] fetch software from SWH archive into EaaSi emulator - compile - execute - use
  - [] FAIR for software with SWH archive
