Identify the exact resource, its licence and attribution requirements before publication or redistribution.

The answer in 30 seconds
Open data permits reuse under stated conditions. Different files in a project may come from different producers, and a portal's general terms cannot replace the licence attached to the specific dataset.
Open the dataset record, identify its named licence and version, read the conditions at the source, and keep the producer, dataset URL and update date with the reused data.
Examples to adapt
Credit the source and link to the dataset page, not merely the downloaded CSV.
Record the licence of each input rather than assigning one source's licence to all rows.
Ask the producer or seek another dataset; do not assume the file is unrestricted.
Follow the method
- 1Locate the record
Find the producer's dataset page and match it to the file you obtained.
- 2Identify the licence
Read the named licence, version and any resource-specific notes.
- 3Plan attribution
Preserve the producer, title, URL, update date and changes you make.
- 4Check the proposed use
Compare your publication or redistribution plan with the licence terms; seek specialist advice when the rights are unclear.
A checklist to keep
Use these checks to record what you found. The grid supports a decision; it does not make one for you.
| Check | What to examine | Action |
|---|---|---|
| Resource | Is this the exact file reused? | Match |
| Producer | Who published it? | Record |
| Licence | Which version applies? | Read |
| Obligations | What credit or sharing is required? | Apply |
| Changes | What did you alter? | Disclose |

What to check
Publicly downloadable does not mean public domain.
Attribution and share-alike obligations can differ.
Personal data concerns may remain even when a dataset has a licence.
Common questions
Can I change the dataset?
Check the named licence; many open licences allow modification with conditions, but the exact terms govern.
Is a link enough for attribution?
Follow the specific licence; retaining producer, title and a stable source URL makes attribution more useful.
