**MediaCrawler is distributed under a custom Non‑Commercial Learning License 1.1, which permits use, modification, and redistribution only for non‑commercial learning and research purposes.**

MediaCrawler, an open‑source media content crawling framework maintained by NanmiCoder, ships with a purpose‑built license designed to balance educational access with protective restrictions. Understanding the **MediaCrawler license terms** is essential before deploying the code in any environment, as the conditions differ significantly from permissive alternatives like MIT or Apache‑2.0.

## Key Restrictions of the MediaCrawler License

The `LICENSE` file at the repository root defines three binding constraints that govern all use of the software:

- **Non‑commercial use only** — Any deployment must serve learning, research, or personal study objectives. Commercial exploitation requires explicit written consent from the author.
- **No large‑scale or disruptive crawling** — Automated collection at volume, or any activity that risks impairing target platform operations, is prohibited without authorization.
- **Attribution preservation** — Redistributed copies must retain the original copyright notice and complete license text.

These terms reflect the author's intent to provide the codebase as an educational resource while mitigating risks of misuse against content platforms.

## Where the License Is Defined

| File | Purpose |
|------|---------|
| `LICENSE` | Full legal text of Non‑Commercial Learning License 1.1 |
| [`README.md`](https://github.com/NanmiCoder/MediaCrawler/blob/main/README.md) | High‑level project overview with compliance reminders |
| [`pyproject.toml`](https://github.com/NanmiCoder/MediaCrawler/blob/main/pyproject.toml) | Build metadata referencing license classification |

## Verifying the License Programmatically

When integrating MediaCrawler into automated workflows or compliance tooling, you can extract and validate license terms directly from the source tree. The following Python utilities read the `LICENSE` file and confirm the permitted use category:

```python
import pathlib

# Resolve path relative to project root

license_path = pathlib.Path(__file__).parents[1] / "LICENSE"

def read_license():
    """Read and return the full license text."""
    with license_path.open(encoding="utf-8") as f:
        return f.read()

def is_non_commercial_use_allowed():
    """
    Confirm the license contains the identifying phrase
    for Non‑Commercial Learning License classification.
    """
    return "Non‑Commercial Learning License" in read_license()

if __name__ == "__main__":
    print("License excerpt:")
    print("\n".join(read_license().splitlines()[:5]))
    print("\nIs non‑commercial learning use permitted?", is_non_commercial_use_allowed())

```

This pattern enables CI/CD pipelines to flag repository inclusions that carry usage restrictions incompatible with commercial product builds.

## How the MediaCrawler License Compares to Standard OSS Licenses

| License | Commercial Use | Modification | Redistribution | Warranty Disclaimer |
|---------|--------------|--------------|----------------|---------------------|
| **Non‑Commercial Learning License 1.1** | ❌ Prohibited | ✅ Permitted | ✅ With conditions | ✅ Present |
| MIT | ✅ Permitted | ✅ Permitted | ✅ Permitted | ✅ Present |
| Apache‑2.0 | ✅ Permitted | ✅ Permitted | ✅ Permitted | ✅ Present |
| GPL‑3.0 | ✅ Permitted* | ✅ Permitted | ✅ Copyleft required | ✅ Present |

*GPL‑3.0 permits commercial use but requires source disclosure for distributed derivatives.

The **MediaCrawler license** occupies a restrictive middle ground: more permissive than proprietary EULAs for educational scenarios, yet more constrained than conventional open‑source licenses for commercial deployment.

## Compliance Checklist Before Using MediaCrawler

Per the `LICENSE` text as implemented in NanmiCoder/MediaCrawler, verify your intended use against these criteria:

1. **Purpose classification** — Confirm the project serves learning, research, or non‑profit academic goals.
2. **Scale assessment** — Ensure crawling volume stays below thresholds that would strain target platforms.
3. **Attribution chain** — Maintain unmodified copies of the `LICENSE` file in all distributions, including Docker images and forked repositories.
4. **Consent documentation** — Obtain and archive written approval from the author for any commercial or large‑scale exceptions.

## Summary

- MediaCrawler uses the **Non‑Commercial Learning License 1.1**, a custom restriction‑based license.
- Permitted uses are limited to **non‑commercial learning and research** with mandatory attribution.
- **Commercial and large‑scale crawling** require explicit written consent from the author.
- The full legal text resides in the repository's **`LICENSE`** file; build metadata appears in **[`pyproject.toml`](https://github.com/NanmiCoder/MediaCrawler/blob/main/pyproject.toml)**.
- Programmatic verification scripts can extract and validate license compliance status from source distributions.

## Frequently Asked Questions

### Can I use MediaCrawler for a commercial data aggregation product?

No. The MediaCrawler license explicitly prohibits commercial use without the author's written consent. Any revenue‑generating deployment, including SaaS offerings and paid internal tools, falls outside the granted permissions. Contact the repository maintainer directly to negotiate alternative licensing terms.

### Is MediaCrawler open source if it restricts commercial use?

MediaCrawler is **source‑available** rather than **open source** under the Open Source Initiative definition. While the full source code is publicly accessible and modifiable, the non‑commercial restriction disqualifies it from OSI‑approved open‑source classification. The license aligns more closely with "ethical source" or "source‑available" paradigms.

### What happens if I violate the MediaCrawler license terms?

The license disclaims all warranties and limits author liability, but copyright infringement claims remain viable. Unauthorized commercial use or large‑scale deployment without consent constitutes breach of license, potentially exposing violators to DMCA takedown requests, injunctive relief, or statutory damages under applicable copyright law.

### How do I request commercial use permission for MediaCrawler?

The [`README.md`](https://github.com/NanmiCoder/MediaCrawler/blob/main/README.md) and `LICENSE` files do not specify a formal application process. Best practice is to open a GitHub issue in the NanmiCoder/MediaCrawler repository describing your intended use case, scale, and commercial context, or locate contact information in the author's GitHub profile for direct licensing inquiries.
