Description

Adds two end-to-end use-case demos under design_decisions/data_sources/: Barcelona (AMB bus GTFS) and Stockholm (SLB air quality for the low emission zone).

Barcelona AMB demo (barcelona_demo/, linked from barcelona.md)

• validate_gtfs.sh: checks required GTFS files, record counts, referential integrity (trips → routes, stop_times → stops/trips) and feed validity dates.
• profile_gtfs.sh: routes per operator, busiest lines, wheelchair-accessible stops and modes.
• bcn-amb-gtfs.workflow.yaml: EDC management API workflow (asset, policy, contract definition, catalogue, negotiation, transfer) reusing the request shapes from test 2.2.3.1A. Hosts, API key and the MobilityDCAT-AP theme URI are placeholders.

Run on 2026-10-21 against AMB feed version 20261021 (8,295,351 bytes, sha256 bc87858b…cddc3b):

validate_gtfs.sh  RESULT: PASS
  11 agencies, 140 routes, 4970 stops, 30145 trips, 950579 stop_times
  trips -> routes 0 orphans · stop_times -> stops 0 orphans · stop_times -> trips 0 orphans
profile_gtfs.sh
  busiest line M19 Badalona-Barcelona (1092 trips) · wheelchair-boarding stops 1888 of 4970 (38%)

Stockholm LEZ demo (stockholm_demo/, new stockholm.md)

SLB-analys (provider) shares NO2, PM10 and noise with Trafikkontoret (consumer) for low emission zone follow-up.

• fetch_slb.sh: hourly NO2 and PM10 from the open SLB API (public key lvl1).
• analyse_slb.sh: mean, peak, latest, busiest hour and days above the WHO 2021 24 h guidelines (NO2 25, PM10 45 µg/m³).
• slb-tk-lez.workflow.yaml: EDC calls with a policy limited to TK and the purpose LEZ-follow-up. The EnviroSuite noise key is referenced only as a vault secret name.

Run on 2026-10-21 for Norrlandsgatan 21, 7–21 Oct (675 hourly records):

analyse_slb.sh
  NO2   mean 11.8  peak 44.3 at 2026-10-19T11:00  days above WHO 24h guideline (25): 1 of 13
  PM10  mean 9.1   peak 30.4 at 2026-10-15T09:00  days above WHO 24h guideline (45): 0 of 13

Neither connector workflow has been executed against live connectors yet; both are ready-to-fill collections with placeholder hosts, DIDs and keys.
