# Open Source Repository Data Sources

Open Navigator treats **open source community projects as first-class citizens** alongside government jurisdictions and nonprofit organizations. This document lists civic tech and community infrastructure repositories related to public engagement.

---

## 🌐 Why Open Source Matters for Civic Engagement

Open source projects are critical infrastructure for:
- **Transparency Tools** - Code that powers government data platforms
- **Civic Tech Solutions** - Community-built tools for local engagement
- **Digital Public Goods** - Shared resources for common challenges
- **Collaboration Networks** - Where maintainers and contributors work together

**Mapping to Open Navigator Concepts:**
- **Repositories** → "Jurisdictions" (each repo is a community)
- **Maintainers/Contributors** → "Decision Makers" (people who merge PRs)
- **Issues/Pull Requests** → "Causes" (opportunities to contribute)
- **Sponsors/Funding** → "Financial Documents" (GitHub Sponsors, grants)

---

## 📊 Data Collection Strategy

### Step 1: Curated Lists (High Quality)
**Sources:**
- Code for America brigade index
- U.S. Digital Response portfolio
- Civic Tech Field Guide registry
- Digital Public Goods catalog

**Method:**
```python
# Ingest curated project lists
from discovery.github_civic_projects import CivicTechIngestion

civic = CivicTechIngestion()
repos = await civic.ingest_curated_lists([
    'codeforamerica',
    'usdigitalresponse',
    'civic-tech-field-guide'
])
```

### Step 2: Topic-Based Discovery (Broader Coverage)
**Sources:**
- GitHub topic search API
- Repository recommendations
- Network analysis (forks, stars from civic repos)

**Method:**
```python
# Search by civic tech topics
topics = [
    'civic-tech',
    'open-government',
    'public-data',
    'community-organizing'
]

for topic in topics:
    repos = await github_api.search_repositories(
        query=f"topic:{topic}",
        sort='stars',
        order='desc'
    )
```

### Step 3: Metadata Enrichment
**Collect:**
- ✅ Repository description and README
- ✅ Primary language and tech stack
- ✅ Active contributors and maintainers
- ✅ Open issues (potential "causes")
- ✅ Sponsorship/funding information
- ✅ License type (must be open source)

## 🎯 Integration with Open Navigator

### People Finder
**Add maintainers and core contributors:**
- Name and GitHub profile
- Role: "Open Source Maintainer" or "Core Contributor"
- Organization: Repository name
- Contact: GitHub username, email (if public)

**Example:**
```
Name: Jane Developer
Role: Core Maintainer
Organization: openbudgetoakland/openbudget
Contact: @janedev on GitHub
```

### Causes
**Map GitHub issues to advocacy opportunities:**
- Issue title → Cause name
- Labels → Topic tags
- "good first issue" → Entry-level causes
- Issue comments → Community engagement level

**Example:**
```
Cause: Add Spanish translation to budget tool
Repository: openbudgetoakland/openbudget
Urgency: Medium (15 community reactions)
How to Help: PR accepted, translation guide provided
```

### Budget/Funding
**Track project sustainability:**
- GitHub Sponsors monthly revenue
- Grant funding (from README or website)
- OpenCollective/Patreon backing
- Corporate sponsorships
