Nepomuk, da KDE ma'anar tebur

Ba zan yi muku karya ba: abin da ya ba ni sha’awa NepomukTun kafin in san abin da yake, ita ce karamar tambarinta (ka sani, launukan pastel, hoda da azurfa: abin yarinya). Bayan binciken tambarin, sai na mai da hankali kan samfurin ... Nepo menene?

Nepomuk es "Amsar KDE zuwa teburin ma'ana". Ya kunshi wani tsarin aiki ƙirƙira da shawara metadata na kowane irin kayan aiki.

… Kamar?

Bari mu je Wikipedia don shakatawa menene metadata

Metadata (na Girkanci Ƙari, makasudin, "Bayan" da latin datum, «Me aka bayar», «dato»), A zahiri« game da bayanai », su ne bayanan da ke bayanin wasu bayanan. Gabaɗaya, rukuni na metadata yana nufin ƙungiyar data, wanda ake kira hanya. Ma'anar metadata daidai take da amfani da fihirisa don gano abubuwa maimakon bayanai. Misali, laburare yana amfani da shafuka wadanda ke tantance marubuta, taken, masu buga takardu, da wuraren neman littattafai. Sabili da haka, metadata yana taimakawa wajen gano bayanai.Domin fannoni daban-daban na ƙididdiga, kamar dawo da bayanai ko gidan yanar gizo na fassara, metadata a cikin alamomi muhimmiyar hanya ce ta daidaita yanayin ma'anar.

Da kyau, da zarar mun tsarkake, bari mu koma zuwa gare shi. Nepomuk. Me zai yi min? Don nemo albarkatu ta hanyar metadata wanda ƙila ko sauƙaƙe (ko bayyane) ga mai amfani na kowa.

Lokacin da muke magana game da metadata, zamu iya sanya shi cikin manyan rukuni uku:

• Takaddun bayanan takamaiman fayil.
• Metadata da mai amfani ya kirkira (alal misali, alama ko ƙididdiga waɗanda galibi muke ƙarawa zuwa na mp3).
• Metadata wanda ba za'a iya samun saukinsa ba.

A karshen shine wurin da zamu iya amfani da damar yin amfani da bayanai da kuma rarrabasu ta hanyar metadata, ma'ana, ta amfani da tebur mai ma'ana.

Misali:

1. Mai amfani ya zazzage abin da aka makala na imel. Lokacin da aka ajiye abin da aka makala a faifai, to bayanan wadanda suka aiko da imel din da kuma uri daga inda aka saukar da imel din sun bata.
2. Tsarin darajar aikace-aikace, fayiloli, da dai sauransu. na masu amfani. Misali, wanene mai amfani wanda yafi yawan rubutawa zuwa disk sda1? Wane mai amfani ne ya sami lambar fakiti mafi yawa?

Nepomuk yafi hadewa da Soprano, Strigi da K MetaData. Soprano tsari ne na daidaitaccen abu don RDF bayanai y ihu abu ne mai sauƙi ɗan bincike. KMetaData ita ce laburaren da ke ba da damar isa ga metadata.

Zuwa yanzu zaku kasance cikin damuwa tare da ma'anarta da kalmomin baƙin, amma ƙarin ma'anar ɗaya don bayyana: Mene ne RDF bayanai?

Duk da yake XML yare ne don samfurin bayanai, RDF yare ne don tantance metadata. XML ya gaza a ma'aunin bayanan tunda tsarin abubuwan da ba na al'ada bane kuma kiyaye shi yana da matukar wahala da tsada, akasin haka, RDF o Tsarin Bayani na Kayan aiki (RDF) yana ba da damar cudanya tsakanin aikace-aikacen da ke musayar bayanai masu fahimta a shafin yanar gizon, don samar da abubuwan more rayuwa waɗanda ke tallafawa ayyukan metadata.

Así cewa, asali, amfani da wannan nau'in kayan aikin zai ba mu damar:

• Samu bayanai "ba bayyane ba" kuma a yatsan ku game da bayanai akan PC din ku. Misali, kaga masu amfani da shirye-shirye wadanda, ta hanyar karanta lambar tushe na aikace-aikacen da suka fi so, zasu iya samun bayanai game da bayanan wadanda suka tsara shi.

• Za'a iya haɓaka damar masu sarrafa kunshin ƙwarai ta hanyar yin amfani da wadatattun wadatattun bayanai waɗanda ke cikin fakiti (misali .deb's) Gaskiyar iya ba shi ƙimar kimantawa za ta sauƙaƙa ƙudurin dogaro ko rikice-rikice. Da amfani. Ko da kafin warware wani rikici (yawanci ana tambayar mai amfani don tabbatarwa), yana iya tuntuɓar bayanan mai amfani da shi kuma zai iya yin amfani da tabbatarwar don warware rikicin. Wannan zai zama da amfani, amma ban sake yarda da haka ba.

• Amfani da Strigi tare da wasu ayyukan kernel na Linux (kamar su Inotify subsystem) zamu iya sake gyara fayilolin da aka gyara mu adana yin bincike akai-akai a cikin duk tsarin fayil ɗin. Anan aikace-aikacen zasu iya samar da metadata da yawa dangane da tsarin tsarin kuma kamar yadda rajistan ayyukan fayilolin rubutu ne bayyane can ana iya amfani dashi.

ƙarshe: idan kai, ƙaunataccen aboki mai karatu, yi amfani da KDE 4 da kyau zaka iya gwadawa Nepomuk. Yana ɗaukar ɗan lokaci kafin a girbe fa'idodi (kuyi tunanin yin tanadin abubuwa da kuma gano metadata akan duk fayiloli akan tsarin…) amma na kiyasta cewa tare da ci gaba da amfani, kayan aiki ne masu ƙarfi.

Ina fatan kun fahimta, na bar ku kuma na ci gaba da gwada wannan babban kayan aikin.

PS: mai rikitarwa sami bayani game da Nepomuk cewa an rubuta shi da kalmomin fahimta kuma ba cikin tsohuwar Sanskrit ba kamar yadda yake a wasu wasu shafuka ... Abin farin ciki, na sami wannan rubutun a cikin Infosofia a matsayin abin dubawa.
