Run SPARQL queries via the Ottgaz Query Service.
Remember: SPARQL is currently case sensitive, as elastic search is disabled in wikibase.cloud.
Namespace
Declare these namespaces at the start of every query:
PREFIX og: <https://ottgaz.org/entity/> PREFIX ogs: <https://ottgaz.org/entity/statement/> PREFIX ogv: <https://ottgaz.org/value/> PREFIX ogt: <https://ottgaz.org/prop/direct/> PREFIX ogp: <https://ottgaz.org/prop/> PREFIX ogps: <https://ottgaz.org/prop/statement/> PREFIX ogpq: <https://ottgaz.org/prop/qualifier/>
Sample queries
Label
All regions that had vilayet status, as well as their English language label. run
SELECT ?vilayet ?vilayetLabel WHERE { ?vilayet ogt:P15 og:Q5. SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" } }
Duration, start and end dates
Duration between start and end date of every region with a start date, as well as region type. run
SELECT ?regionLabel ?statusLabel (YEAR(?starttime) as ?start) (YEAR(?endtime) as ?end) ?duration WHERE { ?region ogt:P6 og:Q1. ?region ogp:P15 ?statement. ?statement ogps:P15 ?status. ?statement ogpq:P7 ?starttime. OPTIONAL{?statement ogpq:P8 ?endtime.} OPTIONAL{?statement ogpq:P22 ?endtime.} BIND(year(?endtime)-year(?starttime) as ?duration ) SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" } } ORDER BY desc(?duration)
Number of kazas created each year
In each year, how many kazas were inaugurated? run
SELECT ?year (COUNT (DISTINCT ?kaza) AS ?count) WHERE { ?kaza ogt:P15 og:Q3. ?kaza ogp:P15 ?statement. ?statement ogps:P15 og:Q3. ?statement ogpq:P7 ?starttime. bind(year(?starttime) as ?year) } GROUP BY ?year ORDER BY desc(?count)
Count status types in a given year
For a given year, how many regions of each status are found in the dataset? run
SELECT (COUNT (DISTINCT ?region) AS ?count) ?statusLabel WHERE { ?region ogp:P15 ?statement. ?statement ogps:P15 ?status. ?statement ogpq:P7 ?starttime. OPTIONAL{?statement ogpq:P8 ?endtime.} OPTIONAL{?statement ogpq:P22 ?endtime.} #enter same year twice FILTER(YEAR(?starttime) <= 1600 && YEAR(?endtime) > 1600) SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" } } GROUP BY ?statusLabel ORDER BY desc(?count)
Number of kazas between 1800 and 1900
- This query is not working yet.* The query below returns the number of vilayets between 1750 and 1760. Thanks to Stanislav Kralin for help. [ run]
PREFIX wd: <http://www.wikidata.org/entity/> PREFIX wdt: <http://www.wikidata.org/prop/direct/> SELECT ?number (count(*) as ?count) { SERVICE <https://query.wikidata.org/sparql> { ?year wdt:P31 wd:Q21199 ; wdt:P1181 ?number FILTER (?number >= 1750 && ?number <= 1760) } ?vilayet ogt:P15 og:Q5. ?vilayet ogp:P15 ?statement. ?statement ogps:P15 og:Q5. ?statement ogpq:P7 ?starttime. OPTIONAL{?statement ogpq:P8 ?endtime.} OPTIONAL{?statement ogpq:P22 ?endtime.} BIND (YEAR(?starttime) AS ?year1) BIND (YEAR(COALESCE(?endtime, NOW())) AS ?year2) FILTER (?number >= ?year1 && ?number <= ?year2) } group by ?number order by ?number
Sancak status ending between 1830 and 1840
This query will return the region more than once, if it undergoes status change more than once during this time period. run
SELECT ?sancak ?sancakLabel (YEAR(?starttime) as ?start) (YEAR(?endtime) as ?end) WHERE { ?sancak ogt:P6 og:Q1. ?sancak ogp:P15 ?statement. ?statement ogps:P15 og:Q4. ?statement ogpq:P7 ?starttime. OPTIONAL{?statement ogpq:P8 ?endtime.} OPTIONAL{?statement ogpq:P22 ?endtime.} FILTER(YEAR(?endtime) >= 1830 && YEAR(?endtime) <= 1840) SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" } } ORDER BY (?endtime)
Map of sanjak seats
This shows only those sanjaks with seats designated and geolocated. run
#defaultView:Map SELECT ?sancakLabel ?seatLabel ?geo WHERE { ?sancak ogt:P15 og:Q4. ?sancak ogt:P14 ?seat. OPTIONAL {?seat ogt:P10 ?geo.} SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" } }
Status count
Which regions have the most status changes entered in Ottgaz? run
SELECT (COUNT (DISTINCT ?statement) AS ?statementCount) (COUNT (DISTINCT ?status) AS ?statusCount) ?regionLabel WHERE { ?region ogp:P15 ?statement. ?statement ogps:P15 ?status. SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" } } GROUP BY ?regionLabel ORDER BY desc(?statementCount) LIMIT 100
Federated query with Wikidata
For every sanjak in Ottgaz, this query fetches the vilayet or eyalet to which Wikidata says it belongs. Thanks to Lucas Werkmeister for help. run
PREFIX og: <https://ottgaz.org/entity/> PREFIX ogt: <https://ottgaz.org/prop/direct/> PREFIX wd: <http://www.wikidata.org/entity/> PREFIX wdt: <http://www.wikidata.org/prop/direct/> SELECT ?sancak ?sancakLabel ?vilayet ?vilayetLabel WHERE { ?sancak ogt:P15 og:Q4 . # item must be a sanjak ?sancak ogt:P4 ?c . # finds reference URL to wikidata BIND(IRI(REPLACE(REPLACE(REPLACE(STR(?c), "Property:", ""), "/wiki/", "/entity/"), "https://", "http://")) AS ?wd_c) # produces proper URL for query form SERVICE <https://query.wikidata.org/sparql> { ?wd_c wdt:P131 ?vilayet . # finds containing vilayet in Wikidata SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". ?vilayet rdfs:label ?vilayetLabel. # finds label in Wikidata } } SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". ?sancak rdfs:label ?sancakLabel. # finds label in Ottgaz } }
Cleanup queries
These queries are useful to find information gaps to be filled when tidying the dataset.
Missing labels
Returns labels in English, Ottoman, and Arabic. Sort results to find blanks. run
SELECT ?seat ?seat_en ?seat_ota ?seat_ar WHERE { ?seat ogt:P6 og:Q6421. OPTIONAL {?seat rdfs:label ?seat_en filter (lang(?seat_en) = "en")}. OPTIONAL {?seat rdfs:label ?seat_ota filter (lang(?seat_ota) = "ota")}. OPTIONAL {?seat rdfs:label ?seat_ar filter (lang(?seat_ar) = "ar")}. }
Seats without geolocation
Wikidata ID can be used to supply geolocation. run
SELECT ?sancak ?sancakLabel ?seat ?seatLabel ?wikidata WHERE { ?sancak ogt:P15 og:Q4. ?sancak ogt:P14 ?seat. MINUS {?seat ogt:P10 ?geo.} OPTIONAL {?seat ogt:P3 ?wikidata.} SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" } }
Seats without regions
During the initial setup, certain regions listed seats, but there was no reciprocal listing of region for the seat items. This query includes date qualifiers, where present. run
SELECT ?region ?regionLabel ?seat ?seatLabel ?starttime ?endtime ?latestdate WHERE { ?region ogt:P14 ?seat. MINUS {?seat ogt:P11 ?region.} OPTIONAL { ?region ogp:P14 ?statement. ?statement ogps:P14 ?seat. ?statement ogpq:P7 ?starttime. OPTIONAL { ?statement ogpq:P8 ?endtime.} OPTIONAL { ?statement ogpq:P22 ?latestdate.} } SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" } }
