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

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

code.nasa.gov

• AngularJS/Bootstrap powered site integrated with GitHub
• Listing of NASA Open Source projects (186 currently)
• Site driven by Open Source Catalog
• Includes Open Source from field center specific sites
• Search Projects, SRA contact info, Process information

Code Sharing Next Steps

• External/Open Source Community Focused
  • Provide additional capabilities for citizens to engage with NASA open source via code.nasa.gov
  • Build "solution-space" features to nurture SpaceApps and similar software projects
• Internal NASA Code Sharing
  • Heterogenous Federated Code Sharing System
  • Repositories (GIT / SVN / Hg / CVS / Custom)
  • Supports
    • Distributed Repository Browsing
    • Full-text Search of Source Code
    • Faceted Search of Projects
  • Leverage Data Standards to model Software Projects

Demo

Demonstrate Search and Browse of Software Repositories in Federated System

Distributed Software Registry

• Problem: Need a way to describe Software Projects using a standard controlled vocabulary 
• How: Leverage Data On A Project (DOAP) RDF vocabulary to model software assets
• Challenge: Need a simplified way to allow software owners create/manage descriptions
• Solution: Create a framework to allow authoring of project descriptions which are easy for developers to use, but create metadata descriptions with enough specificity 

Thanks/Questions

Backup

API.nasa.gov

• Why API Management is needed
  • Increasing number of APIs
  • Finer-grained resource allocation
  • API access control
• Deployment vs. Management
  • mgmt layer sits in front of deployment (e.g.: micro-service)
• Features
  • Caching, Rate Limiting, API Keys
  • Provides hooks for analytics

API.nasa.gov

• Next Steps
  • Add more APIS
  • Two currently in the works:
    • MSL Raw Images API
    • Horizons API 
    • Characterized Piezoelectric and Magnetostrictive Material API

NAMS

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