Nepomuk, i KDE semantic desktop

Andizukuxoka kuwe: yintoni enomdla kum malunga nayo NepomukNgaphambi kokuba ndazi ukuba yintoni, yayiyimpawu yakhe encinci (uyazi, imibala ye-pastel, ipinki kunye nesilivere: into yentombazana). Emva kokuphanda ilogo, ndiye ndagxila kwimveliso ... Nepo yintoni?

Nepomuk es "Impendulo ye KDE kwi-semantic desktop". Iqukethe i- sikhokelo ukudala nokubonisana imethadatha yalo naluphi na uhlobo lobutyebi.

… Njenge?

Masiye kwiWikipedia ukuze sihlaziye yintoni imethadatha

Metadata (ye IsiGrike umz, meta, "Emva" kunye IsiLatini i datum, «Yintoni enikiweyo», «dato»), Ngokwenene« malunga nedatha », idatha echaza enye idatha. Ngokwesiqhelo, iqela lemethadatha libhekisa kwiqela ledatha, elibizwa Ukuphinda. Umxholo wemethadatha uyafana nokusebenzisa izalathiso ukukhangela izinto endaweni yedatha. Umzekelo, ilayibrari isebenzisa iithebhu ezichaza ababhali, izihloko, abapapashi, kunye neendawo zokukhangela iincwadi. Ke, imethadatha inceda ukufumana idatha.Kwimimandla eyahlukeneyo yekhompyuter, njengokufumana ulwazi okanye iwebhu ye-semantic, imethadatha kwiithegi yindlela ebalulekileyo yokuvala uluhlu lweesemantic.

Ewe, xa sele icociwe, masibuyele kuyo. Nepomuk. Izakwenza ntoni kum? Ukufumana izixhobo ngokusebenzisa imethadatha enokuthi okanye ingenakufikeleleka ngokulula (okanye icace) kumsebenzisi oqhelekileyo.

Xa sithetha ngemethadatha, sinokuyibeka kumaqela amathathu amakhulu:

• Imethadatha ekhethekileyo yefayile.
• Imethadatha eyenziwe ngumsebenzisi (umzekelo, iithegi okanye iireyithingi esihlala sizongeza kwi-mp3's).
• Imethadatha engenakufumaneka ngokulula.

Okokugqibela kulapho esinokuthi sithathe khona isalathiso sokwahlulahlulahlulahlulahlulahlulahlulahlula kudidi, oko kukuthi, kusetyenziswa i-semantic desktop.

Umzekelo:

1. Umsebenzisi ukhuphela okuncamathiselwe kwi-imeyile. Xa uncamathiselo lugcinwa kwidiski, izingqinisiso zabo bobabini bathumele i-imeyile kunye ne-uri apho ikhutshelwe khona i-imeyile zilahlekile.
2. Ukuveliswa kohlobo lokufakwa kwezicelo, iifayile, njl. Abasebenzisi. Umzekelo, ngubani umsebenzisi obhala kakhulu kwidiski sda1? Ngowuphi umsebenzisi oneepakethi ezona zininzi zifunyenweyo?

I-Nepomuk yenziwa ikakhulu yile Soprano, Strigi kunye K MetaData. umsundulu sikhokelo esijolise kwinto ye Idatha yeRDF y strigi yidemon elula yokukhangela. KMetaData Ithala leencwadi elenza ukufikelela kwimethadatha.

Okwangoku uzakube ufumana isiyezi ngengcaciso kunye namagama angaqhelekanga, kodwa enye inkcazo yokucacisa: Zintoni Idatha yeRDF?

Ngelixa iXML lulwimi lokumodareyitha idatha, I-RDF lulwimi lokuchaza imethadatha. IXML iyasilela ekukhuleni kwedatha okoko ukulandelelana kwezinto kungokwemvelo kwaye ukugcinwa kwayo kunzima kakhulu kwaye kuyabiza, ngokuchaseneyo, I-RDF o Isikhokelo seNkcazo yezixhobo (RDF) ivumela ukusebenzisana phakathi kwezicelo ezitshintshisa ulwazi oluqondakalayo kwiphepha lewebhu, ukubonelela ngezixhobo ezixhasa imisebenzi yemethadatha.

Así ukuba, ngokusisiseko, ukusetyenziswa kolu hlobo lwezixhobo kungasivumela ukuba:

• Fumana ulwazi "olungacacanga" kunye nasezandleni zakho malunga nedatha kwiPC yakho. Umzekelo, cinga abasebenzisi benkqubo abathi, ngokufunda ikhowudi yemvelaphi yesicelo sabo abasithandayo, banokufumana ulwazi malunga neprofayile yabaphuhlisi abayiphuhlisileyo.

• Amandla abaphathi beephakeji anokunyuswa kakhulu ngokusebenzisa kakhulu ulwazi olucebileyo lweemeta eziqulathwe kwiiphakeji (umz .deb's). Inyani yokukwazi ukuyinika ixabiso le-semantic inokuququzelela isisombululo sokuxhomekeka okanye ukungqubana. Iluncedo. Kwanangaphambi kokuba kusonjululwe ukungavisisani okuthile (ngesiqhelo umsebenzisi ubuzwa ukuba uqinisekisiwe), inokujonga ulwazi lomsebenzisi kunye nokufumana ubungqina bokusombulula ukungavisisani. Oku kunokuba luncedo, kodwa andiqinisekanga kangako.

• Sebenzisa iStrigi ngokudibeneyo kunye nokusebenza kweLinux kernel (enje ngeInotify subsystem) sinokuphinda senze iifayile eziguqulweyo kwaye sigcine ukwenza uphendlo rhoqo kuyo yonke inkqubo yefayile. Apha usetyenziso lunokuvelisa uninzi lweemethadatha ngokunxulumene nenkqubo yenkqubo yokungena kwaye njengoko iinkuni ziifayile ezibhaliweyo ezicacileyo… inokusetyenziswa.

Isiphelo: ukuba wena, mfundi othandekayo ongumfundi, sebenzisa i KDE 4 kakuhle ungazama Nepomuk. Kuthatha ixesha ukuvuna izibonelelo (khawufane ucwangcise ukhangele imethadatha kuzo zonke iifayile ezikule nkqubo…) kodwa ndiqikelela ukuba ngokuqhubeka nokusetyenziswa, sisixhobo esinamandla kakhulu.

Ndiyathemba ukuba uqonda, ndiyakushiya kwaye uqhubeke nokuvavanya esi sixhobo sikhulu.

Saludos !!

P.S: Kunzima kakhulu fumana ulwazi malunga Nepomuk ukuba ibhaliwe kwisigama esiqondakalayo hayi kwiSanskrit yakudala njengakwezinye iisayithi ... Ngethamsanqa, ndiyifumene le posi kwi-Infosofia njengesalathiso.
