Introduction

OCIO CTO for IT, Deborah Diaz is very interested in applying innovation to Code Sharing at NASA

Open Innovation Team (led by Beth Beck) works with developers & SRAs to release open-source

Open Inno. manages code.nasa.gov and operates the NASA GitHub.com organization

Jason Duley (me) leads Code Sharing for Open Innovation and is working to make it better

Process

NAMS

• GitHub.com account provisioning
• NASA Organization participation is managed by NAMS
• GitHub accounts mapped to nasa.gov email

Which Internet-Repo?

• There are several popular sites:
  • GitHub (GIT), SourceForge (SVN/GIT/Hg), BitBucket (GIT/Hg)
• Due to popularity, ease of use and rich feature set - GitHub.com is platform of choice
• GitHub makes up majority of repositories currently
• BitBucket, SourceForge can be used!
• Project Hosting on Google Code - end of life Jan 25, 2016

GitHub.com

http://github.com/nasa 

NASA Organization

• 80 Public Repositories
• 130+ users
• 50+ Development Teams
• 18/50 Private Repositories
• and growing ...

Open Source Catalog

• Make NASA open-source participation more community-driven
• Modeled after DARPA work with open source catalogs
• Catalog feeds code.nasa.gov

https://github.com/nasa/Open-Source-Catalog

• Next: 2 ways to contribute to Open Source Catalog and publish on code.nasa.gov

Open Source Catalog

Add your project the easy way (send us the details)

1. Go here 

https://raw.githubusercontent.com/nasa/Open-Source-Catalog/master/required_fields_project_template.json

2. Download a copy of the above file

3. Edit the file with your project specifics

{
    "NASA Center": "Ames Research Center",
    "Contributors": ["jasonduley"],
    "Software": "My New Software Project",
    "External Link": "https://github.com/nasa/my-new-software-project/wiki",
    "Public Code Repo": "https://github.com/nasa/my-new-software-project",
    "Description": "A project I am registering into the NASA org",
    "License": [ "NASA Open Source" ],
    "Categories": ["Framework","Toolkit","Web"],
    "Update_Date": "2015-05-05"
}

4. Send us the file and we'll update the Catalog

code.nasa.gov

• Formerly a Wordpress Site, now AngularJS/Bootstrap powered
• Listing of NASA Open Source projects
• Site driven by Open Source Catalog
• Currently adding Open Source from field center specific sites
• Search Projects, SRA contact info, Process information

Code Sharing Next Steps

• Internal NASA Code Sharing
  • Heterogenous Federated Repositories (GIT / SVN / Hg / CVS / Custom)
  • Supports
    • Distributed Repository Browsing
    • Full-text Search of Source Code
    • Attribute/Faceted Search
  • Provide App Recipes - build apps from distributed software components
  • Leverage existing Data Standards to model Software (DOAP)

Demo

• Goal: Demonstrate Full-Text Search and Browse of Software Repositories in Federated System
• Demo flow ...
  • Search for a keyword
  • Keyword is not found
  • Add some source code to a repo
  • Incremental indexer runs
  • Redo the search on updated index
  • View the Search hit
  • Show browsing repos in the federation
