Re: [Wiki Loves Monuments] Linked open data?

Maarten Dammers, 14/07/19 15:04: Maybe http://www.ksamsok.se/in-english/ , but I know more about http://data.nationallibrary.fi/bib/sparql and related. They changed the license a few times, I think. When we imported it, it was CC-BY-3.0-it which is fine because it waives the sui generis rights completely. I guess it wouldn't harm. Matching municipalities is often a major pain. The amount of "open data" which is released with usable references to municipalities is negligible, usually you end up manually matching names or codes in free text form in some CSV. Importing the entire of the ontology itself can be trickier. More work on this side has been done by ICCU and ICCD (the ministry): usually it takes them a few years of manual work to connect an ontology. For our import it was more important to handle the objects which had very little (structured) information. The more detailed descriptions are usually sparsely used (in this case you linked, only by one province which was cataloguing first world war damages? I don't know). We used the SPARQL queries listed at the end of the page: <https://www.wikidata.org/?curid=30576438#Reports_for_cleanup_and_data_improvement>. I don't remember if federated queries were fast enough at the time to be usable, I only remember using them for small subsets of the data. As far as I can see the bot is coded to get all the data at once and then see what needs doing. It doesn't attempt to get incremental updates with federated queries. <https://github.com/synapta/wikidata-mibact-luoghi-cultura/blob/master/bot-mibact-to-wikidata/queries.js> Federico
