LCC Interaction Specification: Data Collator a(data_collator(Seq,Best), C) :: filter_results(Seq,Results,Best) a(poller(Seq,Peers,Results), C) sources(Peers) a(poller(Seq,Peers,Results), C) :: ( a(data_seeker(Seq,D,Matches), C) Peers = [D|RestPeers] and Results = [r(D,Matches)|RestResults] then a(poller(Seq,RestPeers,RestResults), C) ) or null Peers = [] and Results = []. a(data_seeker(Seq,D,Matches), S) :: query(Seq) => a(data_source, D) then filter_matches(Seq,Results,Matches) matched(Results) <= a(data_source, D). data_source You can be a data collator for a sequence, seeking the best matches of you can filter the results from polling your peers for their best matches You can poll a set of your peers for their best results if you become a data seeker for the first of these peers and the matches from that peer are merged with the matches you get from polling the rest of the set of peers; or if the set of peers is empty you have no matches You can be a data seeker asking a peer for a set of matches if you send a message to that peer asking it to be a data source then filter the matches it sends back to you in its response

14
LCC Interaction Specification: Data Sharing sharing a(data_source, D) :: query(Seq) <= a(data_seeker(Seq,D,Matches), S) then ( matched(Results) => a(data_seeker(Seq,D,Matches), S) matching_sequences(Seq,Results) or ( a(data_collator(Seq,Results), D) not(matching_sequences(Seq,_)) then matched(Results) => a(data_seeker(Seq,D,Matches), S) ) ). You can be a data source if you get a query from a data seeker and then you send out the matching sequences to the data seeker if these matching sequences can be obtained locally; or you become a data collator, seeking results from others if there are no local matching sequences and then you send out these matching sequences to the data seeker.
