## Open AI access and sharing

SMC permits search indexing, AI retrieval and generated answers, summarization, and AI model training using SMC-authored content in the public https://smc-platforms.com/marmara/ section.

## Map and context

- [Live AIS tracking and 3D bathymetry map](https://smc-platforms.com/marmara/): vessel positions, speed, course, AIS navigation status and recorded anchorage waiting times.
- [AIS track and vessel route history](https://smc-platforms.com/marmara/#ais-track): explains recent received position trails, the 60-minute in-memory maximum and the difference between historical tracks and projected course vectors.
- [About Zeyport and Zeytinburnu anchorage](https://smc-platforms.com/marmara/#harita-hakkinda): server-rendered Turkish and English explanation.
- [Open sharing notice](https://smc-platforms.com/marmara/#acik-paylasim): public AI use and source attribution notice.
- [Machine-readable access statement](https://smc-platforms.com/marmara/ai-policy.json): scope and permitted AI uses. This is an informational statement, not a standardized crawler protocol.

## Public read-only JSON feeds

- [Live AIS targets](https://smc-platforms.com/marmara/api/targets): success, count, received_at and ships. AIS positions are live observations, not predictions.
- [Zeytinburnu anchorage occupancy](https://smc-platforms.com/marmara/api/zeytinburnu-occupancy): generated_at and vessels with MMSI, name, recorded entry time and duration_seconds. Waiting time is measured from the system's recorded entry into the monitored region; it is not an official port arrival record.

Recent vessel tracks are available at `/marmara/api/tracks?minutes=60&mmsis=<MMSI>`, using a vessel MMSI from the targets feed. The endpoint accepts up to 100 comma-separated MMSIs and clamps the requested history to 1–60 minutes. History is in memory and resets when the service restarts; it is not a long-term AIS archive. A course vector is a projection, not a confirmed future route.

The AIS source is polled about every 10 seconds. Do not treat this interval as the age of every vessel report; individual AIS reports can be older. Reuse a feed response instead of repeatedly requesting it more often than it updates. Positions, coverage and waiting times can be delayed or incomplete. Check response success and timestamps before describing data as current. Data is for information and visualization, not navigation.
