I’ve written my understanding in that github thread. Also, database rights are often misunderstood - for example, in my understanding, they do not pertain to any collection of data, but only a subset of it. E.g. from DIRECTIVE 96/9/EC:
Article 3
Object of protection
- In accordance with this Directive, databases which, by reason of the selection or arrangement of their contents, constitute the author’s own intellectual creation shall be protected as such by copyright. No other criteria shall be applied to determine their eligibility for that protection.
You publish a list of your shops. There is no really “reason of the selection or arrangement of their contents” (nor is it likely “author’s own intellectual creation”), so that does not seem to apply.
Article 7
- Member States shall provide for a right for the maker of a database which shows that there has been qualitatively and/or quantitatively a substantial investment in either the obtaining, verification or presentation of the contents to prevent extraction and/or re-utilization of the whole or of a substantial part, evaluated qualitatively and/or quantitatively, of the contents of that database.
Willfully publicly publishing a list of your shops IMHO does not constitute “substantial investment in either the obtaining, verification or presentation of the contents to prevent extraction and/or re-utilization”, to the contrary (now if such data was hidden behind paywall or similar it would be different).
Article 6
Exceptions to restricted acts
- The performance by the lawful user of a database or of a copy thereof of any of the acts listed in Article 5 which is necessary for the purposes of access to the contents of the databases and normal use of the contents by the lawful user shall not require the authorization of the author of the database. […]
seems to imply to me that such content made available publicly by their creator for the explicit purpose of people finding their shops should thus not require the authorization for “normal use of the content” (e.g. openly publishing the database of opening hours of your shops on the web should not prevent you from looking up location or opening_hours
of those shops in say OsmAnd using OSM database so you can go there buy stuff).
Article 8
Rights and obligations of lawful users
2. A lawful user of a database which is made available to the public in whatever manner may not perform acts which conflict with normal exploitation of the database or unreasonably prejudice the legitimate interests of the maker of the database.
also seems to confirm that - looking up location of the shop is IMHO quite “normal exploitation of the database (of locations of the shops)”
- Whereas the special right to prevent unauthorized extraction and/or re-utilization relates to acts by the user which go beyond his legitimate rights and thereby harm the investment; whereas the right to prohibit extraction and/or re-utilization of all or a substantial part of the contents relates not only to the manufacture of a parasitical competing product but also to any user who, through his acts, causes significant detriment, evaluated qualitatively or quantitatively, to the investment;
The OSM in my view is not “competing product” to shop publishing the list of their locations publicly on their website, nor it would “cause significant detriment to the investment” (to the contrary, it might only bring more business); thus it should not be applicable.
But IANAL, and I have only briefly looked at alltheplaces readme, not deeply investigating what they do or exactly how.
That I agree for any mass import. For individual use, that is likely not a problem from copyright/database rights point, because:
Article 8
Rights and obligations of lawful users
- The maker of a database which is made available to the public in whatever manner may not prevent a lawful user of the database from extracting and/or re-utilizing insubstantial parts of its contents, evaluated qualitatively and/or quantitatively, for any purposes whatsoever […]
I personally would say “yay!” but that is probably not what you wanted to hear - but it you read that github ticket, you’ll see that is quite legally possible (CC0 only waves away your own rights; it specifically disclaims responsibility for obtaining any necessary consents, permissions or other rights required for any use of the Work). IOW, CC0 does not mean what most people probably think it means.
