I-Nepomuk, ideskithophu ye-KDE semantic

Angizukuqamba amanga: yini engangiyithanda ngempela I-NepomukNgisho nangaphambi kokuba ngazi ukuthi kwakuyini, kwakuyilogo yakhe encane (uyazi, imibala ye-pastel, i-pink nesiliva: into yentombazane). Ngemuva kokucwaninga ilogo, ngigxile kumkhiqizo ... Nepo ini?

I-Nepomuk es Impendulo ye-KDE kudeskithophu ye-semantic. Iqukethe i- uhlaka ukwakha nokubonisana imethadatha yanoma yiluphi uhlobo lomthombo.

… Njengoba?

Ake siye kuWikipedia ukuvuselela yini imethadatha

Imethadatha (we IsiGrikhi nxa, meta, "Ngemuva" futhi latin i-datum, «Okunikezwa», «idatha»), Ngokoqobo« mayelana nedatha », idatha echaza enye idatha. Ngenjwayelo, iqembu lemethadatha libhekisa eqenjini ledatha, elibizwa insiza. Umqondo wemethadatha uyafana nokusebenzisa izinkomba ukuthola izinto esikhundleni sedatha. Isibonelo, umtapo wolwazi usebenzisa amathebhu acacisa ababhali, izihloko, abashicileli, nezindawo ukusesha izincwadi. Ngakho-ke, imethadatha isiza ukuthola idatha. Ezinkambeni ezahlukahlukene zekhompyutha, njengokutholwa kolwazi noma iwebhu ye-semantic, imethadatha kumathegi yindlela ebalulekile yokuvala ibanga le-semantic.

Yebo, uma sekucacisiwe, ake sibuyele kuyo. I-Nepomuk. Izongenzela ini? Ukuthola izinsizakusebenza ngemethadatha engafinyeleleka noma engafinyeleleki kalula (noma esobala) kumsebenzisi ojwayelekile.

Uma sikhuluma ngemethadatha, singayibeka ngamaqembu amakhulu amathathu:

• Imethadatha eqondene nefayela.
• Imethadatha eyenziwe ngumsebenzisi (ngokwesibonelo, omaki noma izilinganiso esivame ukuzengeza kuma-mp3's).
• Imethadatha engatholakali kalula.

Kamuva kulapho lapho singasebenzisa ngokunenzuzo ukukhomba nokuhlukanisa ngemethadatha, okungukuthi, sisebenzisa ideskithophu ye-semantic.

Isibonelo:

1. Umsebenzisi ulanda okunamathiselwe kwi-imeyili. Lapho okunamathiselwe kugcinwa kudiski, izinkomba zabo bobabili abathumele i-imeyili ne-uri lapho i-imeyili ilandwe khona zilahlekile.
2. Isizukulwane sesikhundla sezinhlelo zokusebenza, amafayela, njll. wabasebenzisi. Isibonelo, ngubani umsebenzisi obhala kakhulu kwi-disk sda1? Yimuphi umsebenzisi onenani eliphakeme kakhulu lamaphakethe atholiwe?

I-Nepomuk yakhiwe kakhulu ISoprano, iStrigi neK MetaData. Soprano uhlaka oluqondiswe entweni lwe- Imininingwane ye-RDF y strigi iyi-daemon elula yokusesha elula. KMetaData umtapo wezincwadi osiza ukufinyelela kwimethadatha.

Okwamanje uzobe uthola isiyezi ngezincazelo nangamagama angajwayelekile, kodwa enye incazelo eyodwa ukucacisa: Yini Imininingwane ye-RDF?

Ngenkathi i-XML ilulimi lokumodela idatha, I-RDF ilulimi lokucacisa imethadatha. I-XML yehluleka kukwehla kwedatha njengoba ukuhleleka kwezinto kungokwemvelo futhi ukugcinwa kwayo kunzima kakhulu futhi kuyabiza, kunalokho, I-RDF o Uhlaka Lencazelo Yezinsizakusebenza (RDF) ivumela ukusebenzisana phakathi kwezinhlelo zokusebenza ezishintshanisa imininingwane eqondakalayo ekhasini lewebhu, ukuhlinzeka ngengqalasizinda esekela imisebenzi yemethadatha.

Ngakho ukuthi, ngokuyisisekelo, ukusetshenziswa kwalolu hlobo lwamathuluzi kuzosivumela ukuthi:

• Thola imininingwane "engabonakali" futhi kutholakale kalula ngemininingwane eku-PC yakho. Isibonelo, cabanga abasebenzisi bohlelo abathi, ngokufunda ikhodi yomthombo yohlelo lwabo abaluthandayo, bangathola imininingwane mayelana nephrofayili yabahleli abayithuthukisile.

• Amandla abaphathi bamaphakheji angakhuphuka kakhulu ngokusebenzisa kakhulu imininingwane ecebile ye-meta equkethwe kumaphakeji (isb. I-deb's). Iqiniso lokukwazi ukuyinika inani le-semantic lizohlenga ukuxazululwa kokuncika noma izingxabano. Iwusizo. Ngisho nangaphambi kokuxazulula ukungqubuzana okuthile (imvamisa umsebenzisi ubuzwa ukuqinisekisa), ingaxhumana nemininingwane yomsebenzisi uqobo futhi ikwazi ukufaka ukuqinisekiswa kwento ukuxazulula impikiswano. Lokhu kuzoba wusizo, kepha angisaqiniseki kangako.

• Sisebenzisa iStrigi ngokuhlangana nokusebenza okuthile kwe-Linux kernel (efana ne-Inotify subsystem) singakwazi ukuhlanganisa kabusha amafayela aguquliwe futhi sigcine ukwenza ukusesha okuvamile kulo lonke uhlelo lwefayela. Lapha izinhlelo zingakhiqiza imethadatha eningi maqondana ne-log yesistimu futhi njengoba izingodo zingamafayili wombhalo ocacile… ingasetshenziswa.

Isiphetho: uma wena, mngane othandekayo womfundi, sebenzisa i-KDE 4 kahle ungazama I-Nepomuk. Kuthatha isikhashana ukuvuna izinzuzo (cabanga ukufaka inkomba nokusesha imethadatha kuwo wonke amafayela asohlelweni…) kepha ngilinganisela ukuthi ngokusetshenziswa okuqhubekayo, kuyithuluzi elinamandla kakhulu.

Ngiyethemba uzwisisile, ngiyakushiya futhi ngiyaqhubeka nokuhlola leli thuluzi elikhulu.

Saludos !!

P.S: kuyinkimbinkimbi kakhulu thola ulwazi mayelana I-Nepomuk ukuthi ibhalwe ngamagama aqondakalayo hhayi ngesiSanskrit sasendulo njengakwezinye izingosi… Ngenhlanhla, ngithole lokhu okuthunyelwe ku-Infosofia njengesithenjwa.
