# MetaOxide Roadmap - Prioritized by Adoption
**MetaOxide** is a comprehensive structured data extraction library. This roadmap is **ordered by real-world adoption statistics** to maximize impact.
## Vision
Extract ALL structured data from web pages in a single, fast, type-safe library with Python bindings.
## Priority Strategy
**Phases are ordered by adoption rate** - we build what websites actually use first:
1. **100% adoption** → Phase 1 (Standard Meta)
2. **60% adoption** → Phase 2 (Open Graph)
3. **45% adoption** → Phase 2 (Twitter Cards)
4. **41% adoption ↗️** → Phase 3 (JSON-LD - HIGHEST IMPACT)
5. **26% adoption ↘️** → Phase 4 (Microdata)
6. **5-10% adoption** → Phase 7 (Microformats - LOW priority)
7. **<10% adoption** → Phase 8+ (RDFa, Dublin Core - VERY LOW)

## Why This Order?
### Old Approach (Wrong)
Started with microformats (5-10% adoption) because it seemed simple.
### New Approach (Correct)
1. **Standard Meta (100%)** - Everyone needs this
2. **Open Graph + Twitter (60%+45%)** - Social sharing is critical
3. **JSON-LD (41% ↗️)** - SEO, AI, future-proof, GROWING
4. **Microdata (26% ↘️)** - Still used, declining
5. **Utilities (oEmbed, etc.)** - High value despite moderate adoption
6. **Microformats (5-10%)** - Niche but valuable for IndieWeb
7. **Legacy (RDFa, Dublin Core)** - Very niche
### Impact vs Effort
| Standard Meta | 100% | Critical | Low | Do First |
| Open Graph | 60% | Very High | Low | Do First |
| Twitter | 45% | Very High | Low | Do First |
| JSON-LD | 41% ↗️ | Highest | Medium | Do Second |
| Microdata | 26% ↘️ | Medium | Medium | Do Third |
| oEmbed | Moderate | Medium-High | Medium | Do Third |
| Microformats | 5-10% | Low-Medium | Low | Later |
| RDFa | <10% | Low | Medium | Much Later |
| Dublin Core | <5% | Very Low | Low | Last |

## Key Changes from Previous Roadmap
### What Changed?
1. **Microformats moved from Phase 1 → Phase 7**
- Reason: Only 5-10% adoption
- Still valuable for IndieWeb, but not priority
2. **Standard Meta moved to Phase 1**
- Reason: 100% adoption, foundation
3. **JSON-LD emphasized as HIGHEST IMPACT**
- Reason: 41% and growing, enables Rich Results, AI/LLM training
- E-commerce: 41% adoption (critical)
4. **Social (OG+Twitter) is Phase 2**
- Reason: 60%+45% adoption, immediate value
5. **New phases added for utilities**
- oEmbed, verification, PWA
- Moderate adoption but high utility
### What Stayed?
- Python bindings approach
- Rust performance focus
- Type-safe design
- Comprehensive documentation
---
## Unified API Design
Same API as before, but returned data reflects priority:
```python
import meta_oxide
data = meta_oxide.extract_all(html, base_url=url)
# Returns (in priority order):
{
# Phase 1 (100%)
"meta": {
"title": "...",
"description": "...",
"canonical": "..."
},
# Phase 2 (60%+45%)
"opengraph": {
"title": "...",
"image": "...",
"type": "article"
},
"twitter": {
"card": "summary_large_image",
"title": "..."
},
# Phase 3 (41% ↗️)
"jsonld": [
{
"@type": "Article",
"headline": "..."
}
],
# Phase 4 (26% ↘️)
"microdata": [...],
# Phase 7 (5-10%)
"microformats": {
"h-entry": [...],
"h-card": [...]
},
# Phase 9 (<10%)
"rdfa": [...],
# Phase 10 (<5%)
"dublin_core": {...}
}
```
