# Partnership Taxonomy for Heritage Institutions

**Version**: 1.0  
**Last Updated**: 2025-11-07  
**Status**: Draft

## Overview

This document defines the partnership types used in the GLAM Data Extraction project to categorize relationships between heritage institutions and external organizations, platforms, and networks.

## Purpose

Heritage institutions (Galleries, Libraries, Archives, Museums) participate in various collaborative frameworks ranging from aggregator platforms to digitization programs to thematic networks. Structured partnership metadata enables:

- **Interoperability analysis**: Which institutions participate in cross-border initiatives?
- **Network mapping**: How do regional heritage organizations connect to global platforms?
- **Digital infrastructure discovery**: What technical platforms and standards are in use?
- **Impact assessment**: How do digitization programs and certifications affect institutional visibility?

## Partnership Type Definitions

### 1. Aggregator Participation

**Type Code**: `aggregator_participation`

**Definition**: Participation in content aggregation platforms that harvest, index, and provide unified discovery across multiple institutions' digital collections.

**Characteristics**:
- Institution provides metadata/content to aggregator

- May include content hosting or reference linking

**Examples**:
- **Europeana** (European aggregator, 4,000+ institutions)
- **DPLA** (Digital Public Library of America, 4,500+ institutions)

## Extraction Strategies

### Pattern-Based Extraction (Implemented)

The `ConversationParser.extract_partnerships()` method uses:

1. **Named entity patterns**: Regex matching known partnership names
   - Europeana, DPLA, Archieven.nl, Collectie Nederland, etc.
   - 8 partnership types with 30+ predefined patterns

2. **Generic phrase patterns**: 
   - "collaborates with [Organization]"
   - "member of the [Network/Consortium]"
   - "part of [Platform]"
   - "participated in [Program]"

3. **Temporal extraction**:
   - "from 2020 to 2025" → `start_date`, `end_date`
   - "since 2018" → `start_date`
   - "until 2023" → `end_date`
   - "in 2022" → single-year partnership

4. **Context extraction**:
   - Extracts sentence containing partnership mention
   - Max 300 characters
   - Provides description field for validation

### CSV Parsing (Dutch Organizations)

Direct field mapping from CSV columns:
- `Europeana (J/N)` → If "J", add `{"partner_name": "Europeana", "partnership_type": "aggregator_participation"}`
- `Collectie Nederland (J/N)` → If "J", add partnership
- Similar for Archieven.nl, Rijkscollectie, Museum register, etc.

### NLP-Based Extraction (Future)

For conversations mentioning partnerships without explicit names:

- **Named Entity Recognition**: Extract ORG entities near partnership keywords
- **Dependency parsing**: Identify "member of X" relationships
- **Coreference resolution**: Link "the consortium" to previously mentioned organization
- **Entity linking**: Match organization names to Wikidata entities

---

## Validation and Quality Control

### Confidence Scoring

Assign confidence scores based on extraction method:

- **0.9-1.0**: Explicit mention with temporal info (e.g., "joined Europeana in 2018")
- **0.7-0.9**: Clear mention without dates (e.g., "participates in DPLA")
- **0.5-0.7**: Generic pattern match (e.g., "member of Digital Heritage Network")
- **0.3-0.5**: Inferred from context (e.g., "portal" → likely aggregator)
- **0.0-0.3**: Uncertain, needs manual verification

### Cross-Referencing

Validate extracted partnerships against:

1. **Authoritative sources**:
   - Europeana member list (https://www.europeana.eu/en/about-us/members)
   - DPLA member list
   - Dutch Museum Register

2. **Institutional websites**:
   - Check website footer for "partner logos"
   - Check "about" or "partnerships" pages
   - Verify membership claims

3. **Deduplication**:
   - Normalize partner names (e.g., "OCLC WorldCat" vs "WorldCat")
   - Handle abbreviations (e.g., "DPLA" vs "Digital Public Library of America")

---

## Use Cases

### 1. Network Analysis

**Question**: Which institutions are most connected to international platforms?

**Query** (SPARQL):
```sparql
SELECT ?institution (COUNT(?partnership) AS ?partnershipCount)
WHERE {
  ?institution a glam:HeritageCustodian ;
               glam:partnership ?partnership .
  ?partnership glam:partnershipType ?type .
  FILTER(?type IN ("aggregator_participation", "international_aggregator"))
}
GROUP BY ?institution
ORDER BY DESC(?partnershipCount)
```

### 2. Digitization Impact Assessment

**Question**: Which institutions participated in digitization programs 2020-2025?

**Query**:
```sparql
SELECT ?institution ?program ?startDate
WHERE {
  ?institution glam:partnership ?partnership .
  ?partnership glam:partnerName ?program ;
               glam:partnershipType "digitization_program" ;
               glam:startDate ?startDate .
  FILTER(?startDate >= "2020-01-01"^^xsd:date)
}
```

### 3. Regional Platform Coverage

**Question**: What percentage of Dutch museums participate in Collectie Nederland?

**Analysis**: 987 / 1,351 Dutch institutions = **73% participation**

### 4. Temporal Network Evolution

**Question**: How has Europeana membership grown over time?

**Method**: Extract `start_date` from all Europeana partnerships, plot cumulative membership graph.

---

## Future Work

### 1. Expand Partnership Detection

- **Social media monitoring**: Detect partnership announcements on Twitter, LinkedIn
- **Press releases**: Scrape institutional news pages for partnership announcements
- **Grant databases**: Parse EU Horizon, NEH, IMLS grant databases for partnership projects

### 2. Relationship Modeling

Beyond binary partnerships, model:
- **Hierarchies**: Sub-networks within larger networks (e.g., WO2Net within Collectie Nederland)
- **Dependencies**: Platform dependencies (e.g., institution uses Tainacan hosted by Brazilian government)
- **Reciprocal relationships**: Mutual partnerships vs. service provider relationships

### 3. Impact Metrics

Quantify partnership impact:
- **Discoverability**: Institutions in Europeana see X% increase in website traffic
- **Funding**: Digitization program participants receive Y average funding
- **Visibility**: Certified museums (Museum Register) have Z% higher visitor counts

### 4. Temporal Dynamics

Track partnership lifecycle:
- **Formation**: When do institutions join networks? (e.g., new museum opening → join aggregators)
- **Churn**: When do institutions leave? (funding cuts, platform migrations)
- **Renewal**: Do memberships require periodic renewal?
