IB: Semantic web daim ntaub ntawv yog qhov tseeb uas cob qhia cov neeg focusing muaj ntau dua qhov twg.Near yav tag nrho rau cov qhov web daim ntaub ntawv yuav tau tsim qab semantic architecture thiab lub ntsiab lus. Jena API thiab RDF tej pob khoom siv mus cuag lub hom phiaj.
Cov ntsiab lus semantic yog ib lub npe loj heev thiab kuv yuav tham txog nws rau hauv txhawb kuv tus ncej tom ntej thiab tseem nyob hauv kuv lub website tech (www.techalpine.com).
Kuv yuav luam tawm tsab nws rau kuv cov BLOG thiab lub website ntawm Nimno kuv kuv ua hauj lwm rau hauv ib tsab semantic web daim ntawv thiab kev pab (www.techalpine.com) rau koj siv.
Tam sim no, Jena yog ib qib API Java semantic Web site yog applicatons. Thiab raws li nws yog ib tug Java API kuv yuav tsum siv nws nyob hauv kuv tsab ntawv teev npe rau lub POC.Tus yuam sij RDF pob rau hauv cov ntaub ntawv tsim tawm no yog com.hp.hpl.jena.rdf.model.RDF “Muab nqe lus piav moj khaum” uas yuav tsum tau txhais tias yog ib hom num ua hauj lwm rau cov sawv cev rau cov ntaub ntawv (feem ntau paub li ' resource’ lub semantic).Jena API muaj tau sau tseg ntawd tej interfaces ua daim ntawv thov cov kev cai yuav ua hauj lwm nrog hom implementations tsis tau hloov. Cov pob no muaj interfaces rau cov sawv cev ua qauv, III., khoom, literals, nqe lus thiab cov lus txhua tus lwm yam tseem ceeb ntawm RDF, thiab ib ModelFactory kev tsim tus qauv.Ces tus tshiab chaws tshua ywj siab rau ntawm qhov kev siv.Lub com.hp.hpl.jena…impl tej pob khoom muaj cov hoob siv uas tej zaum yuav tshwm sim los muaj coob implementations. Piv txwv, lawv nyiaj thiab lub sij kawm ResourceImpl, PropertyImpl, thiab LiteralImpl uas yuav siv tau ncaj qha los yog subclassed los implementations sib txawv.
