2b. XYZ Organisation has data for free download under licence N. Can I use it in OSM?
Approach the data owners, explain OSM, and seek written permission to licence their data under our licence and contributor terms.
Unless the data is genuinely offered without any restrictions on use at all (i.e. public domain), please contact the Licensing Working Group for advice. Do not rely on your own legal interpretation of the licence. OSM is all about creating a freely and easily redistributable data set. Anything which taints the dataset or exposes OSM to possible legal action interferes with that objective.
Even if you only want to use a minor part, or compare the sources, you should still seek approval in writing. The legal principles involved are not well developed, and the OSM community wants to develop a free and untainted dataset and not test any of the legal issues involved here.
In short: be ultra-cautious.

Please also note the details of attribution requirement. We can offer some attribution: we can credit them on our website (not on the homepage, but in the Contributors page here on the wiki, and on www.openstreetmap.org/copyright for very large-scale contributions). We can link information about them in relation to the user account performing import edits, meaning the editing history will allow people to trace the source of the data donation. We can also set their name in the ‘source’ tags of our underlying data. This is perhaps more prominent, but may be removed by editors doing further mapping work. The credit to the “author” stops there. **What we certainly cannot do is require end-users of our data/renderings to give credit to the particular data donor. **With this in mind, our attribution may not be sufficient legally speaking and might actually be considered unsatisfactory by the original “authors” of the data.

Edellinen koskettaa juurikin MML:n lisenssin kohtaa: “require third parties to provide the same information when granting rights to copies of dataset(s) or products and services containing such data”

Asia saattaisi selvitä sillä, että MML tarkentaisi mitä tuo edellinen lisenssissän tarkalleen ottaen tarkoittaa. Mielestäni “third parties” tarkoittaa jotakuta, joka edelleenkäyttää OSM tietoa (1st party ollen MML, ja 2nd party olisi OSM). Eli itse tulkitsen asian siten, että MML vaatii (jos MML:n data on importoitu OSM -kantaan), että OSM-aineiston hyödyntäjän tulisi jotenkin tuo MML:n lisenssi huomioida. Saatan tietysti tulkita väärinkin.

Ei tämän tarvitsisi olla näin vaikeaa. Asia selviäisi, jos MML ottaisi selkeän kannan sille, mitä kyseinen kohta lisenssissä tarkoittaa OSM:n kannalta, mihin se velvoittaa OSM:n.
