- People will misinterpret the data
- It’s not very interesting
- I don’t mind making it open, but I worry someone else might object
- Our data is embarrassingly bad
- What if we want to sell access to this data?
- People will contact us to ask about stuff
- There’s no API to that system
- …
- People will misinterpret the data
- Document how it should be interpreted
- It’s not very interesting
- Let others judge how interesting or useful it is
- I don’t mind making it open, but I worry someone else might object
- This is a common deflection
- Our data is embarrassingly bad
- Many eyes will help you improve your data
- What if we want to sell access to this data?
- Can be legitimate, but often isn't

The 5 Stars of Linked Open Data
| ★ | Available on the Web (whatever format) but with an open licence, to be Open Data |
| ★★ | Available as machine-readable structured data (e.g. excel instead of image scan of a table) |
| ★★★ | as (2) plus non-proprietary format (e.g. CSV instead of Excel) |
| ★★★★ | All the above plus, Use open standards from W3C (RDF and SPARQL) to identify things, so that people can point at your stuff |
| ★★★★★ | All the above, plus: Link your data to other people’s data to provide context |
