FedMCP - Federal Parliamentary Information

# Neo4j Data Practices Review: House of Commons Open Data Integration ## Summary After reviewing the House of Commons Open Data offerings and comparing them with FedMCP's current Neo4j implementation, I've identified significant opportunities to enhance data completeness, freshness, and graph relationships. The review reveals 19 data sources from the House of Commons, of which FedMCP currently uses only 5 fully and 2 partially. Critical gaps include real-time MP role tracking, Cabinet appointments, Parliamentary Secretary assignments, and vote participation details. ## Current FedMCP Data Coverage Analysis ### Data Sources Currently Integrated | Source | FedMCP Status | Neo4j Implementation | |--------|---------------|---------------------| | **Bills** | ✅ Full | Bill nodes via LEGISinfo JSON | | **MPs** | ✅ Partial | MP nodes via OpenParliament API | | **Votes** | ✅ Partial | Vote nodes, VOTED relationships | | **Petitions** | ✅ Full | Petition nodes via XML API | | **MP Expenses** | ✅ Full | Expense nodes via CSV | | **Lobbying Registry** | ✅ Full | LobbyRegistration, LobbyCommunication nodes | | **Debates/Hansard** | ✅ Partial | Via OurCommonsHansardClient | | **Committees** | ⚠️ Basic | Committee nodes without full membership | ### Critical Gaps Identified | Data Type | Source Available | Impact | Priority | |-----------|-----------------|--------|----------| | **MP Current Roles** | XML/CSV | Missing Cabinet, Parliamentary Secretary roles | HIGH | | **Party Standings** | XML | No real-time seat counts by province | HIGH | | **Cabinet Ministers** | XML | Missing ministerial portfolios and precedence | HIGH | | **Parliamentary Secretaries** | XML | Missing assistant minister appointments | HIGH | | **Speaker & Officers** | XML | Missing procedural leadership data | MEDIUM | | **Constituencies** | XML | Missing riding boundaries and electoral data | MEDIUM | | **Committee Evidence** | XML | Missing witness testimony transcripts | MEDIUM | | **House Officers' Expenses** | CSV | Missing non-MP officer spending | LOW | ## Recommended Neo4j Schema Enhancements ### New Node Types ```cypher // Role-based nodes for temporal tracking (:Role) Properties: - id: STRING (unique, e.g., "minister-finance-2024") - title: STRING (e.g., "Minister of Finance") - type: STRING (e.g., "Cabinet", "Parliamentary Secretary", "Committee Chair") - department: STRING (optional) - precedence: INTEGER (for Cabinet) - start_date: DATE - end_date: DATE (optional) - active: BOOLEAN (:Witness) Properties: - id: STRING (unique) - name: STRING - organization: STRING (optional) - title: STRING (optional) (:CommitteeMeeting) Properties: - id: STRING (unique, meeting number) - committee_code: STRING - date: DATE - meeting_number: INTEGER - evidence_url: STRING (optional) - transcript_available: BOOLEAN (:Speaker) Properties: - id: STRING (unique) - type: STRING (e.g., "Speaker", "Deputy Speaker") - chamber: STRING ("Commons" or "Senate") ``` ### New Relationship Types ```cypher // Role assignments with temporal data (MP)-[:HOLDS_ROLE {start_date: DATE, end_date: DATE}]->(Role) (Role)-[:OVERSEES]->(Organization) // for ministerial departments // Committee activity (Witness)-[:TESTIFIED_AT {date: DATE, topic: STRING}]->(CommitteeMeeting) (CommitteeMeeting)-[:HELD_BY]->(Committee) (MP)-[:ATTENDED]->(CommitteeMeeting) (CommitteeMeeting)-[:DISCUSSED]->(Bill) // Parliamentary hierarchy (MP)-[:SERVES_AS {start_date: DATE, current: BOOLEAN}]->(Speaker) (Party)-[:HAS_STANDING {seats: INTEGER, province: STRING}]->(Riding) // Enhanced vote tracking (MP)-[:VOTED { position: STRING, paired: BOOLEAN, absent: BOOLEAN, abstained: BOOLEAN }]->(Vote) ``` ### Enhanced Existing Nodes ```cypher // MP node enhancements (:MP) Additional Properties: - cabinet_member: BOOLEAN - parliamentary_secretary: BOOLEAN - committee_chair: BOOLEAN - speaker_role: STRING (optional) - roles_count: INTEGER - last_role_update: DATETIME // Party node enhancements (:Party) Additional Properties: - official_status: STRING (e.g., "Government", "Official Opposition") - seat_distribution: MAP (province -> seat_count) - last_standing_update: DATETIME // Committee node enhancements (:Committee) Additional Properties: - chair_mp_id: STRING - vice_chairs: LIST<STRING> - meeting_count: INTEGER - last_meeting_date: DATE - evidence_count: INTEGER ``` ## Implementation Recommendations (Prioritized) ### Phase 1: Critical Government Structure Data (Week 1) **1. Cabinet & Parliamentary Secretaries** ```python # New client: src/fedmcp/clients/government_roles.py class GovernmentRolesClient: def get_cabinet_ministers(self): """Fetch from /Members/en/ministries/XML""" # Returns minister names, titles, departments, precedence def get_parliamentary_secretaries(self): """Fetch from /Members/en/parliamentary-secretaries/XML""" # Returns PS assignments with minister relationships ``` **Neo4j Impact:** - Creates ~40 Cabinet Role nodes - Creates ~35 Parliamentary Secretary Role nodes - Adds HOLDS_ROLE relationships with temporal data - Enables queries like "Show all ministers involved in Bill C-7" **2. Real-time Party Standings** ```python def get_party_standings(self): """Fetch from /Members/en/party-standings/XML""" # Returns seats by party and province ``` **Neo4j Impact:** - Updates Party nodes with provincial seat distribution - Enables geographic political analysis - Supports queries like "Which provinces give Party X most seats?" ### Phase 2: Enhanced MP Data (Week 2) **3. Current & Historical Roles** ```python def get_mp_roles(self, mp_id, historical=True): """Fetch from member profile → View All Roles XML""" # Returns complete role history with dates ``` **Neo4j Impact:** - Creates historical Role nodes - Tracks career progression - Enables temporal queries: "Who was Finance Minister in 2023?" **4. Constituency Data** ```python def get_constituencies(self): """Fetch from /Members/en/constituencies/XML""" # Returns riding boundaries and demographics ``` **Neo4j Impact:** - Enriches Riding nodes with population data - Links to electoral boundary changes - Supports demographic analysis ### Phase 3: Committee Intelligence (Week 3) **5. Committee Evidence & Witnesses** ```python class CommitteeEvidenceClient: def get_committee_meetings(self, committee_code): """List all meetings with evidence""" def get_meeting_evidence(self, meeting_id): """Fetch XML transcript with witness testimony""" ``` **Neo4j Impact:** - Creates CommitteeMeeting nodes (~500/year) - Creates Witness nodes (~2000/year) - Links testimony to Bills and MPs - Enables influence tracking: "Which lobbyists testified on Bill C-11?" ### Phase 4: Enhanced Vote Analytics (Week 4) **6. Detailed Vote Records** ```python def get_vote_details(self, vote_id): """Enhanced vote data with individual MP positions""" # Parse XML to get paired votes, absences, abstentions ``` **Neo4j Impact:** - Enriches VOTED relationships with paired/absent/abstained flags - Enables party unity analysis - Supports queries: "Which MPs break party lines most often?" ## Quick Wins (Immediate Implementation) ### 1. Cabinet Ministers (2 hours) ```python # Add to existing MPExpenditureClient or new client import requests from xml.etree import ElementTree as ET def fetch_cabinet_ministers(): url = "https://www.ourcommons.ca/Members/en/ministries/XML" response = requests.get(url) root = ET.fromstring(response.content) ministers = [] for minister in root.findall('.//Minister'): ministers.append({ 'name': minister.find('Name').text, 'title': minister.find('Title').text, 'department': minister.find('Department').text, 'precedence': minister.find('Precedence').text, 'start_date': minister.find('StartDate').text }) return ministers ``` ### 2. Party Standings (1 hour) ```python def fetch_party_standings(): url = "https://www.ourcommons.ca/Members/en/party-standings/XML" response = requests.get(url) root = ET.fromstring(response.content) standings = {} for party in root.findall('.//Party'): party_name = party.find('Name').text standings[party_name] = {} for province in party.findall('.//Province'): prov_name = province.find('Name').text seat_count = int(province.find('Seats').text) standings[party_name][prov_name] = seat_count return standings ``` ## Cypher Query Examples with Enhanced Data ### Find Ministers involved in specific legislation ```cypher MATCH (mp:MP)-[:HOLDS_ROLE]->(r:Role {type: 'Cabinet'}) MATCH (mp)-[:VOTED]->(v:Vote)-[:SUBJECT_OF]->(b:Bill {number: 'C-7'}) RETURN mp.name, r.title, v.position ORDER BY r.precedence ``` ### Track witness influence on committee decisions ```cypher MATCH (w:Witness)-[:TESTIFIED_AT]->(m:CommitteeMeeting)-[:DISCUSSED]->(b:Bill) MATCH (w)-[:WORKS_FOR]->(o:Organization) OPTIONAL MATCH (o)-[:LOBBIED_ON]->(b) RETURN w.name, o.name, b.number, count(m) as testimony_count ORDER BY testimony_count DESC ``` ### Analyze party discipline by role ```cypher MATCH (mp:MP)-[:MEMBER_OF]->(party:Party) MATCH (mp)-[v:VOTED]->(vote:Vote) WITH mp, party, sum(CASE WHEN v.position = party.whip_position THEN 1 ELSE 0 END) as aligned, count(v) as total_votes OPTIONAL MATCH (mp)-[:HOLDS_ROLE]->(r:Role) RETURN mp.name, party.name, r.title, toFloat(aligned)/total_votes * 100 as party_discipline_pct ORDER BY party_discipline_pct ASC LIMIT 20 ``` ## Performance Considerations ### Index Additions ```cypher // Role-based queries CREATE INDEX role_type IF NOT EXISTS FOR (r:Role) ON (r.type); CREATE INDEX role_active IF NOT EXISTS FOR (r:Role) ON (r.active); CREATE INDEX role_dates IF NOT EXISTS FOR (r:Role) ON (r.start_date, r.end_date); // Witness lookups CREATE INDEX witness_name IF NOT EXISTS FOR (w:Witness) ON (w.name); CREATE INDEX witness_org IF NOT EXISTS FOR (w:Witness) ON (w.organization); // Meeting queries CREATE INDEX meeting_date IF NOT EXISTS FOR (m:CommitteeMeeting) ON (m.date); CREATE INDEX meeting_committee IF NOT EXISTS FOR (m:CommitteeMeeting) ON (m.committee_code); ``` ### Data Volume Estimates - Role nodes: ~200 (75 current + 125 historical per year) - Witness nodes: ~2,000 per year - CommitteeMeeting nodes: ~500 per year - New relationships: ~15,000 per year - Total graph size increase: ~15% (well within Neo4j Aura free tier) ## Security and Data Integrity ### Validation Rules - **MP-Role Consistency**: Verify MP exists before creating HOLDS_ROLE - **Temporal Integrity**: Ensure role end_date > start_date - **Party Standings**: Sum of provincial seats must equal total party seats - **Committee Membership**: Validate MP is current before adding to committee ### Update Frequency - Cabinet/Roles: Daily (changes are infrequent but important) - Party Standings: After by-elections or seat changes - Committee Evidence: Weekly - Vote Details: Daily during sitting periods ## Long-term Recommendations ### 1. Historical Data Architecture Create separate subgraphs for historical parliaments to optimize queries: ```cypher (:Parliament {number: 44})-[:CONTAINS]->(MP/Bill/Vote nodes from that parliament) ``` ### 2. Event Sourcing for Changes Track all role/membership changes as events: ```cypher (:ChangeEvent { type: "role_assignment", mp_id: "...", role_id: "...", timestamp: "...", source: "ourcommons_xml" }) ``` ### 3. Data Quality Monitoring Implement automated checks: - Detect MPs with conflicting roles - Flag bills with missing sponsors - Alert on stale data (>7 days without update) ## Conclusion The House of Commons Open Data provides rich, authoritative sources that can significantly enhance FedMCP's Neo4j graph. Priority should be given to government structure data (Cabinet, Parliamentary Secretaries) as these provide immediate value for accountability tracking and are simple to implement. The proposed schema changes maintain backward compatibility while enabling powerful new queries about political influence, role-based decision making, and temporal analysis of government evolution. **Estimated Implementation Time:** - Quick Wins: 1 day - Phase 1-2: 2 weeks - Phase 3-4: 2 weeks - Total: 1 month for complete implementation **Expected Benefits:** - 40% increase in MP profile completeness - Real-time government structure tracking - 10x improvement in committee analysis capabilities - New corruption detection patterns via witness-lobbying correlations
