We’d like to be able to query by timestamp; specifically, we want to be able to find all statements that were made within a given time range. Is this what I should be looking at? https://cwiki.apache.org/confluence/download/attachments/63407907/Rya%20Temporal%20Indexing.pdf?version=1&modificationDate=1464789502000&api=v2

Do you need to be able to query by timestamp, or simply discover the timestamp for a given node? Rya does have a temporal index, but that requires you to use a temporal ontology to model the temporal properties of your graph nodes. ________________________________________ From: Liu, Eric <[email protected]> Sent: Wednesday, February 22, 2017 6:38 PM To: [email protected] Subject: Timestamps and Cardinality in Queries Hi, Continuing from our talk earlier today I was wondering if you could provide more information about how timestamps could be queried in Rya. Also, we are trying to support a type of query that would essentially be limiting on cardinality (different from the normal SPARQL limit because it’s for node cardinality rather than total results). I saw in one of Caleb’s talks that Rya’s query optimization involves checking cardinality first. I was wondering if there would be some way to tap into this feature for usage in queries?
