- I-Metadata ulwazi oluchaza olunye ulwazi futhi luyisihluthulelo sokuhlela, ukusesha, ukuhumusha, kanye nokuvikela izinsiza zedijithali.
- Ukuhlukaniswa okuvame kakhulu kuwahlukanisa abe yizinhlobo ezichazayo, ezokuphatha kanye nezakhiwo, kanye nezinhlobo zobuchwepheshe, zamalungelo kanye nezokulondolozwa.
- Ziphinde zihlelwe ngokwezingqikithi zazo, ukuguquguquka kwazo, kanye nomsebenzi eziwenzayo ngaphakathi kohlelo lolwazi.
- Ukuphathwa kahle kwemethadatha kuthuthukisa ukusebenzisana, ukuthobela imithetho, ukuphepha, ukuhlaziya okuthuthukisiwe, kanye nembuyiselo ekutshalweni kwezimali.
Kuleli qophelo, cishe konke esikwenzayo kushiya umkhondo wedijithali: i-imeyili, isithombe, umbiko, ividiyo, noma okuthunyelwe okulula kwezokuxhumana. Kanye nalokhu okuqukethwe kuhamba ungqimba olungabonakali kodwa olubalulekile: imethadatha . Lokhu kusebenza njengelebula, kuchaza ukuthi iyini insiza ngayinye, ivelaphi, nokuthi kufanele iphathwe kanjani.
Umqondo oyisisekelo ulula: imininingwane echaza eminye imininingwane . Ngezinye izikhathi ivezwa njengemininingwane ehlukile kokuqukethwe okuyinhloko, njengokuthi ubani ongumnikazi wethebula, ifayela linamafomethi anjani, noma ukuthi lashintshwa nini. Ngezinye izikhathi zihlanganiswe kakhulu kangangokuthi kunzima ukuhlukanisa ukuthi idatha iphela kuphi nokuthi incazelo yayo iqala kuphi.
Iyini imethadatha futhi kungani ibalulekile?
Ayikho incazelo eyodwa eyamukelwa emhlabeni wonke. Incazelo ebanzi kakhulu ithi ziyidatha echaza eminye idatha , kodwa futhi zakhiwe njengolwazi mayelana nedatha, idatha mayelana nolwazi, noma ulwazi mayelana nolwazi. Emikhakheni yobuchwepheshe, njengokuxhumana ngocingo kanye nesayensi yekhompyutha, ziqondwa njengolwazi olungavamile ukuhambisana nomsebenzisi wokugcina, yize lubalulekile ohlelweni olucela, olubuyekeza, noma oluphatha ulwazi. Ku-biology, isibonelo, zisetshenziswa njengezincazelo ezijwayelekile zezici zesethi yedatha , okuhlanganisa umongo lapho ziqoqwe khona kanye nezindinganiso ezisetshenziswayo.
Umngcele phakathi kwedatha kanye ne-metadata awucaci ngaso sonke isikhathi. Inkondlo ingaba okuqukethwe okuyinhloko futhi, ngesikhathi esifanayo, ibe yi-metadata uma ixhunywe engomeni njengezingoma. Kwenzeka into efanayo ngesihloko sombhalo: iyingxenye yomsebenzi futhi iyichaza. Yingakho singakhuluma ngisho nange -metadata mayelana ne-metadata , okuzwakala kungavamile kodwa kusiza, isibonelo, ukwazi ukuthi ibhulokhi ngayinye yolwazi ivelaphi lapho kuhlanganiswa izithombe ezimbili nezincazelo zazo.
Ukubaluleka kwazo kukhule ngobuningi bedatha ephathwa yizinhlangano. Uma ziphathwa kahle, zithuthukisa ukufinyeleleka nokuzulazula ezindaweni zokugcina ezinkulu, ziguqula ulwazi olungavuthiwe lube ulwazi oluwusizo, futhi zivumela abasebenzisi ukuthola idatha ethile ngaphandle kokubuyekeza yonke isethi yedatha. Inkampani yokuthengisa ingathola izibalo zokuthengisa zenyanga, zihlungiwe ngesigaba nesifunda, ngaphandle kokusesha ngesandla kuwo wonke amarekhodi ayo. UGartner ulinganisele ukuthi izinkampani ezingasebenzisi indlela eqhutshwa yimethadatha yokuthuthukisa i-IT yazo zingachitha imali efinyelela ku-40% ekuphathweni kwedatha.
Izizindalwazi, izinhlelo zokuphatha okuqukethwe, kanye nemitapo yolwazi yedijithali ithembele kuzo ukuhlela, ukuthola, nokuphatha ulwazi. Uma idatha ihlelwe kahle, amabhizinisi angakwazi ukusebenzisa kangcono ubuhlakani bebhizinisi, ubuhlakani bokwenziwa, kanye nezinhlelo zokufunda komshini. Ngaphezu kwalokho, idatha igcina ikhwalithi yedatha, ubuqotho, kanye nozalo , futhi yenza kube lula ukuhambisana nemithetho efana ne-GDPR, CCPA, ISO 27001, HIPAA, kanye ne-LGPD.
Zisetshenziselwani ekuphileni kwansuku zonke?
Ukuhlela nokuthola ulwazi kungomunye wemisebenzi yayo eyaziwa kakhulu: kuvumela abasebenzisi ukuthi bahlukanise amadokhumenti, izithombe, noma amafayela futhi basheshise ukusesha kwangaphakathi. Kwenza futhi kube nokwenzeka ukwenza izinqubo ngokuzenzakalela , njengokuhlukanisa amadokhumenti ngobuhlakani bokwenziwa, ukunciphisa isikhathi kanye namaphutha omuntu lapho kufakwa amalebula ezintweni ezibucayi.
Ngokuphathelene nemithethonqubo, ziyasiza ekuboneni ukuthi idatha yomuntu siqu igcinwa kuphi nokuthi iphathwa kanjani, into edingekayo yizinhlaka ezifana ne-GDPR, i-ISO 27001, kanye ne-HIPAA. Zivumela ukulungiswa kokuhlolwa okunembe kakhudlwana kanye nokugwema izinhlawulo. Ngaphezu kwalokho, zinikeza ukulandelelwa kanye nokulawulwa kwenguqulo : ukuthi ubani ofinyelele idatha, yini eshintshile, futhi nini, enikeza ukucaca ezindaweni ezisebenzisanayo noma ezilawulwa kakhulu.
Ngokuphepha, zisetshenziselwa ukuchaza izinqubomgomo zokufinyelela, ukuthola amadokhumenti abalulekile, nokuvimbela ukufinyelela okungagunyaziwe. Izixazululo ezisekelwe ku-AI, njenge-Kriptos, zisebenzisa lolu lwazi ukuvimbela ukuvuza kwedatha futhi zihlukanise ulwazi ngokuzenzakalelayo ngokuya ngokuzwela. Ezinye izinhlelo zokusebenza ezingacacile zifaka phakathi ukuhluza imibuzo yenjini yokusesha, ukuvala igebe le-semantic, ukumela ulwazi, ukwenza lula ukuhamba komsebenzi okunefomethi ehlukahlukene, ukuthuthukisa ukucindezelwa kwamavidiyo, kanye nokuguqula isethulo sokuqukethwe samadivayisi eselula kanye nabasebenzisi abangaboni kahle.
Ukuhlukaniswa okuyinhloko ngokuya ngomsebenzi
Ukwahlukaniswa okuvame kakhulu kuhlukanisa phakathi kwe-metadata echazayo, eyokuphatha, kanye neyesakhiwo. I-metadata echazayo ikhomba futhi ichaze insiza ukuze itholakale futhi iqondwe: isihloko, umbhali, isifinyezo, amagama angukhiye, izihloko ezimboziwe, usuku lokudalwa, usayizi wefayela, kanye nolimi. Lezi ngokuvamile yizinto ezibangela ukusesha kwedokhumenti okuphumelelayo.
Abasebenzi bokuphatha bagxila ekuphathweni kwezinsizakusebenza. Lokhu kufaka phakathi abasebenzi bezobuchwepheshe, abahlela futhi bamele amafayela, bacacise uhlobo lwefayela, usayizi, isixazululo, isofthiwe yokudala, kanye nosuku lokuguqulwa. Kukhona futhi abasebenzi bamalungelo, abaqopha ubunikazi bombhali, imikhawulo yokusetshenziswa, amalayisense ezentengiselwano, kanye namalayisense e-Creative Commons, kanye nabasebenzi bokulondolozwa, abasekela ukulondolozwa kwesikhathi eside; indinganiso ye-PREMIS iyisilinganiso kule ndawo.
Amamaki okwakheka achaza indlela izingxenye zomthombo ezihlelwe ngayo: izahluko encwadini, amakhasi kudokhumenti, amazinga efolda, noma izixhumanisi phakathi kwezingxenye. Lokhu kuhambisana nezilimi zamamaki, ezihlanganisa imethadatha namamaki okwakheka noma okunencazelo ngaphakathi kokuqukethwe ngokwako.
Kwezinye izindlela, amapharamitha okuphatha afaka phakathi izimvume zomsebenzisi, izinqubomgomo zokugcina, amalayisense okusebenzisa, kanye nemithetho yokulondoloza. Amapharamitha okusebenzisa achaza indlela ifayela elisetshenziswe ngayo: inani lokufinyelela, umsebenzisi olifinyelele, noma usuku lokufinyelela kokugcina. Lolu ngqimba luwusizo kakhulu ekuhloleni, ekulinganiseni ukuthandwa, nasekutholeni izinsiza ezikhohliwe.
Ezinye izindlela zokuzihlukanisa
Ngokusekelwe kokuqukethwe kwazo, i-metadata ingahlukaniswa ibe yileyo echaza umthombo wonke kanye naleyo echaza okuqukethwe kwawo. Ngamanye amazwi, eminye ichaza into ngokwayo, kanti eminye ichaza isihloko. Lo mehluko ulula kodwa uwusizo kakhulu ekuklameni amakhathalogi nezinhlelo zokusesha.
Ngokusekelwe ekuguquguqukeni kwazo, i-metadata ingaba yi- immutable , engashintshi kungakhathaliseki ukuthi iyiphi ingxenye yomthombo ebukwayo, njengegama lefayela, noma i- mutable , ehlukahluka kuye ngendawo noma ingxenye ebonakalayo, njengokuqukethwe kwevidiyo. Lokhu kuhlukaniswa kusiza ekunqumeni ukuthi yiziphi izincazelo okufanele zilungiswe nokuthi yiziphi okufanele zibuyekezwe ngokuhamba kwesikhathi.
Kukhona enye indlela yokusebenza, ehlukaniswe yaba izendlalelo ezintathu: idatha engaphansi kwezimpawu, enganikezi incazelo ngokwemvelo; idatha engokomfanekiso, echaza eyokuqala futhi enezela incazelo; kanye nedatha enengqondo, ekhombisa indlela yokusebenzisa idatha engokomfanekiso ukufeza iziphetho. Lo mbono uxhumanisa i-metadata nokumelwa kolwazi kanye nekhono lemishini lokucabanga ngokuzenzakalelayo.
Imethadatha ehlelekile nengahlelekile
Amafayela ahleliwe alandela ifomethi echazwe ngaphambilini, njenge-XML, i-JSON, noma i-CSV. Ajwayelekile futhi ahunyushwa kalula yizinhlelo, ezihlinzeka ngokucubungula okuzenzakalelayo, ukusebenzisana, kanye nokuqinisekiswa okuqhubekayo. Amafayela angahlelekile awanamatheli ohlelweni olufanayo: avela kumbhalo wamahhala, amanothi, amazwana, noma amathegi angakahleleki, futhi kunzima kakhulu ukuwasebenzisa ngezinga elikhulu.
Lo mehluko uchaza ukuthi kungani izinhlangano eziningi zizama ukuguqula izincazelo ezihlakazekile zibe amarekhodi ajwayelekile. Uma i-metadata ihlelwe kahle, ingabiwa kuwo wonke amapulatifomu, iqhathaniswe kuwo wonke ama-repository, futhi isetshenziswe kabusha kumasevisi ahlukene ngaphandle kokuphinda umsebenzi uqale phansi.
Izibonelo ezisebenzayo zemethadatha
Idokhumenti yebhizinisi ihlanganisa isihloko, umbhali, usuku lokudala, amagama angukhiye, kanye nezinga lobumfihlo; isibonelo, umbiko wezezimali wekota yesibili, osayinwe ngu-Ana Torres, onemibandela efana nesabelomali, imali engenayo, kanye nebhalansi, kanye nobumfihlo obuphezulu. Isithombe sedijithali sihlanganisa ukulungiswa, izixhumanisi ze-GPS, usuku, kanye nedivayisi yokuthwebula, njengesithombe samaphikseli angu-4032×3024 esithathwe nge-Samsung Galaxy S23.
Ividiyo yesikhungo ingafaka ubude bayo, ifomethi ye-MP4, isofthiwe yokuhlela efana ne-Adobe Premiere, ulimi lwesiSpanishi, kanye nemibhalo engezansi. Ku-imeyili, i-metadata ifaka umthumeli, abamukeli, isihloko, usuku, isikhathi, kanye nezinamathiselo. Ku-database yobudlelwano, ithebula lamakhasimende lingachazwa ngezinkambu ezifana negama, i-imeyili, izinga lobungozi, kanye nezwe, ngaphezu kosuku lokugcina lokubuyekeza.
Imidiya yezenhlalo nayo iyachuma kulesi sigaba esingabonakali: yonke i-LinkedIn uxhumano, ubungani be-Facebook, noma i-Spotify play idala ubudlelwano namaphethini ahlaziywayo ukuze kunconywe okuqukethwe kanye nokukhangisa okubonisayo. Amafayela e-Word, PDF, kanye ne-JPG agcina izakhiwo ezifana nombhali, usuku lokudalwa, kanye nosayizi, okuwusizo ekusesheni ngosuku noma kumbhali. Ku-HTML, amathegi e-meta ajwayelekile anikeza umbhali, incazelo, amagama angukhiye, kanye nokubuyekezwa kokugcina, kuyilapho amathegi e-HTTP engashintsha izihloko ngezenzo ezifana nokuvuselela ikhasi, ukulondoloza ikhukhi, noma ukukhombisa uhlobo lwedokhumenti.
I-Metadata ekubhaleni, kuwebhu nasekufundeni
Ekubhaleni, zisetshenziselwa ukuhlela izizindalwazi eziphathelene, ukucebisa okuqukethwe kwewebhu nge-SEO kanye ne-Schema.org, ukwenza kube lula ukusebenzisana phakathi kwezinhlelo, kanye nokuvikela ulwazi olusefwini. Ezinhlelweni zamafayela, njenge-HFS noma i-ReiserFS, kanye nasezinjinini zokusesha ezihlakaniphile njenge-Beagle noma i-Spotlight, zisiza ekuqondiseni nasekutholeni izinsiza. Ziphinde zivele kubahleli bezithombe njenge-F-Spot, i-Picasa, noma i-iPhoto, kanye nesofthiwe yokuphatha umculo efunda amathegi e-ID3 kuma-MP3 noma ama-CD, njenge-iTunes kanye ne-Rhythmbox.
Ekufundeni nge-inthanethi, izinto zemfundo kanye nezinsizakusebenza zichazwa ukuze kube lula ukusesha ezindaweni zokugcina izinto. Izinga le-IEEE LOM lichaza izigaba eziyisishiyagalolunye ezivumela ukuthi insiza ichazwe ngokombono wokufundisa kanye nowezobuchwepheshe, ukuthuthukisa ukusetshenziswa kabusha, ukubuyisa, ukusebenzisana, ukuphathwa komjikelezo wokuphila, kanye nokuvikelwa kwamalungelo empahla yobuhlakani. Insiza enomklamo omuhle wokufundisa ayanele: uma i-metadata yayo imbi, ilahlekelwa yinani njengento yokufunda.
I-Paradata ingenye into ehlobene. Ikhiqizwa lapho umsebenzisi exhumana nesisetshenziswa semfundo noma isevisi futhi ngokuvamile iqoshwa njengenhlanganisela yomsebenzisi, isikhathi, isevisi, isisetshenziswa, kanye nomphumela. Ukuhlaziya i-paradata kuvumela ukudalwa kwezincomo, izinhlelo zodumo, ukuboniswa kokuxhumana, kanye nokuhlonza izinkinga noma amathuba okuthuthukiswa. Ngezinye izikhathi igcinwa ku-metadata yesisetshenziswa, kuphrofayela yomsebenzisi, noma, ngokuvamile, kuthebula noma kusizindalwazi esihlukile.
Umjikelezo wokuphila, ukudalwa kanye nokugcinwa
Umjikelezo wokuphila we-metadata uhlanganisa ukudalwa, ukuphathwa kabi, kanye nokubhujiswa. I-metadata ingadalwa ngesandla, ngokuzenzakalelayo kancane, noma ngokuzenzakalelayo. Ukwenziwa ngesandla kuyakhathaza futhi kuncike kufomethi kanye nomthamo, ngezinye izikhathi kuba yinto engasebenzi. Ukwenziwa okuzenzakalelayo kuhlose ukuba nesofthiwe ithole ulwazi ngaphandle kosizo lwangaphandle, yize ukukhipha konke ngomshini kusalokhu kuyinkimbinkimbi. Ngakho-ke, ukwenziwa okuzenzakalelayo kancane kubhekwa njengokungokoqobo: ama-algorithm ayasebenza, futhi umuntu ucacisa ukungabaza noma aphakamise idatha uhlelo olungenakuyikhipha.
Ochwepheshe batusa ukungashiyi ukukhiqizwa kwemethadatha kuze kube sekupheleni, kodwa kunalokho ukuyihlanganisa ngesikhathi sokudalwa kwensiza, ukugcina i-metadata ngokushesha nje lapho ivela, nokusebenzisa ulwazi lomdali wensiza. Uma idatha ishintsha, i-metadata nayo kumele ishintshe; ezinye izinguquko zenziwa ngokuzenzakalela, kodwa ezinye zidinga ukungenelela komuntu. Ukukhiqizwa kwe-Meta—okungukuthi, ukusebenzisa kabusha izingxenye zensiza ukudala ezinye—kwenza kube nzima ukuhlanganiswa kwe-metadata, ikakhulukazi lapho kuhileleke amalungelo edijithali. Ukususwa kudinga nokucatshangelwa ngokucophelela: ngezinye izikhathi kungcono ukususa i-metadata kanye nesisetshenziswa, kanye nezinye izikhathi ukuyigcina ukuze kuqashwe izinguquko.
Kunezindlela ezimbili zokugcina i-metadata: ngaphakathi kwedokhumenti uqobo noma kusisetshenziswa sangaphandle. Ekuqaleni, isitoreji sangaphakathi sasikhethwa ukuze kuphathwe kangcono, kodwa namuhla isitoreji sangaphandle siyathandwa ngoba sihlanganisa i-metadata futhi sithuthukise usesho. Inselele ilele ekuhlanganiseni isisetshenziswa kanye nencazelo; amazinga amaningi asebenzisa ama-URI, kodwa umbuzo usalokhu wokuthi kufanele kwenziweni ngamadokhumenti angenayo i-URI. Amafomethi ashintshe kusukela kumbhalo ocacile noma i-binary kuya ku-XML, efundeka kalula ngabantu kanye nemishini, yize ithatha isikhala esiningi futhi ukuguqula isakhiwo sayo sesihlahla sibe umfudlana wedatha akulula ngaso sonke isikhathi. Ngakho-ke, kunezinsizakusebenza zokuguqula phakathi kwe-XML kanye ne-binary.
Ukuqinisekisa ukufana, kunconywa amagama alawulwayo, achaza amagama ensimini futhi avimbele injini yokusesha ekutholeni "español" (Spanish) kodwa hhayi "española" (Spanish). Ama-ontology aqhubeka futhi achaze ubudlelwano phakathi kwamagama, ukuze umshini uqonde ukuthi uVan Gogh wayengumdwebi waseDashi noma ngabe umsebenzisi usesha "pintores náuticos" (abadwebi baseDashi). Ama-Folksonomies afana, kodwa adalwe abasebenzisi ngokwabo hhayi ochwepheshe.
Izinselele ezivamile, ukugxekwa, nezinkinga
Akuzona zonke izinzuzo. Abanye bagxeka imethadatha ngokuthi ibiza kakhulu, ihamba kancane ukuyikhiqiza, kanye neqiniso lokuthi izinkampani aziboni njalo isidingo esanele. Kuthiwa futhi kuyinkimbinkimbi, ukuthi abantu abawamukeli amazinga ngoba abaziqondi, nokuthi kuncike embonweni nasemongweni: abantu ababili bangachaza umthombo ofanayo ngendlela ehlukile. Ngaphezu kwalokho, awunamkhawulo, ngoba izendlalelo eziningi zingafakwa njalo, kanti abanye bakubheka njengokungadingekile uma bebhekene nezinjini zokusesha ezinamandla kakhulu kanye namasu okusesha, isibonelo.
Empeleni, kuvela izinkinga ezifana nokungapheleli, njengoba ukugcwalisa amarekhodi kuyadina futhi kuvame ukwenziwa kungaphelele uma kunezinkulungwane zezinto noma amasimu amaningi kakhulu. Ukusebenzisana kuyinkimbinkimbi ngoba isikhungo ngasinye singasebenzisa amagama ahlukene esicini esifanayo. Kukhona futhi ukungavumelani kwencazelo, ulwazi olungaphelele, kanye nezincazelo ezibhalelwe abantu imishini ehluleka ukuzicubungula. Noma kunjalo, amafomethi amaningi e-metadata ayathandwa futhi afakazela ukuthi ayasiza lapho eklanywe kahle.
Izindinganiso namafomethi aziwa kakhulu
Amafomethi nezindinganiso ezivamile zifaka phakathi i-ID3 yomsindo we-MP3, i-MPEG-7, i-MPEG-21, i-TV-Anytime, i-EXIF yezithombe, i-Dublin Core, i-LOM yezinto zokufunda, i-RDF, i-RDF Schema, i-OWL, i-NewsML, i-SportsML, i-ONIX yezincwadi embonini yokushicilela, kanye ne-ISO 19115 yolwazi lwendawo. Ngayinye ibhekana nezidingo ezithile futhi ngokuvamile ivela emiphakathini edinga imithetho evamile yokushintshanisa imethadatha yayo.
Inhloso yamasu e-multimedia ukuchaza izinsiza ezithile, kuyilapho iwebhu ye-semantic ihlose ukuchaza izinhlobo zezinsiza nokuxhumanisa ulwazi ndawonye. Lo mehluko ubumba indlela amagama, ama-ontology, kanye nezinhlelo zemibuzo eziklanywe ngayo.
Ukuphepha, ukuthobela imithetho, kanye namathuluzi esimanje
I-Metadata iyimpahla ewusizo yokuphepha kwe-inthanethi kanye nokuthobela imithetho. Ivumela indawo yedatha yomuntu siqu, ukumaka amadokhumenti ngokuya ngokuzwela kwawo, ukusetshenziswa kwezinqubomgomo zokufinyelela, ukukhiqizwa kwemibiko yokuhlola, kanye nokuvimbela ukwephulwa kwedatha. I-Kriptos, isibonelo, isebenzisa ubuhlakani bokwenziwa ukuhlukanisa amadokhumenti abucayi ngokusekelwe ekuhlaziyweni kwe-metadata, ukuhlonza ulwazi olubucayi olufihliwe, ukuwamaka ngokuzenzakalelayo, ukuvimbela ukuvuza, ukudala imibiko yokulawula, kanye nokunikeza ukubonakala okuphelele ohlelweni lolwazi.
Uma kuqhathaniswa namathuluzi endabuko afana namaspredishithi, izinhlelo zokuphatha amadokhumenti eziyisisekelo, noma izinqubo ezenziwe ngesandla, ipulatifomu yesimanje izenzekela ngokuzenzakalelayo ukukhiqiza nokuhlaziya, inciphisa amaphutha kanye nokubandlulula, ihlanganisa ukubonakala, iphoqelela izinqubomgomo ezihambisana nebhizinisi, futhi isebenzisa ukuvikela, ukubethela, ukususa, noma ukususa ukubethela. Ukuthobela imithetho kuba yinto esebenzayo, hhayi ukuhlolwa ngesandla okubizayo. Ngaphezu kwalokho, kulinganisa ukuhlaziya izigidi zamafayela ngemizuzu, kungakhathaliseki ukuthi avelaphi noma ifomethi yawo, futhi ivumelana nezinqubomgomo ezintsha ngaphandle kokulungiswa kabusha okuyinkimbinkimbi.
Ngokuphathelene nokuphepha, umehluko ucacile: izindlela zendabuko azivumeli njalo ukutholakala kwemibhalo ebucayi noma ukuvinjelwa kokufinyelela ngokusekelwe emazingeni obumfihlo, okwandisa ingozi yokuvuza kwangaphakathi. Imbuyiselo ekutshalweni kwezimali nayo iyathuthuka ngokunciphisa izikhathi zokusebenza, ukunciphisa amaphutha, ukwenza imisebenzi ebalulekile ngokuzenzakalela, nokuvimbela izehlakalo ezingalimaza idumela noma ziholele ezijezisweni. Ukuhlukaniswa ngesandla kungase kubonakale kungabizi, kodwa izindleko ezifihliwe zamaphutha, ukungalandeli imithetho, isikhathi esilahlekile, kanye nezingozi zokuphepha kwe-inthanethi zivame ukuba phezulu kakhulu ngokuhamba kwesikhathi.
I-Metadata ingaphezu kakhulu kwamalebula obuchwepheshe: yikhampasi esivumela ukuthi siqonde, sihlele, futhi sivikele ulwazi lwedijithali. Ukuluhlukanisa ngokwemisebenzi, okuqukethwe, noma ukuguquguquka kusiza ukuklama izinhlelo ezingcono, futhi ukuyisebenzisa ngokuhlakanipha kuthuthukisa ukuseshwa, ukusebenzisana, ukuhambisana nemithetho, ukuphepha, kanye nokwenza izinqumo. Endaweni lapho idatha ikhula njalo, ukuqonda lolu ngqimba olungabonakali kwenza umehluko phakathi kokuqongelela ulwazi nokuyiguqula ibe yinani langempela.
