CC - yintoni na le nto?

Kukho zolwazi ezininzi. Ukuze uqonde ukuba yintoni na, kubalulekile ukuqwalasela imixholo yazo. Kodwa kukho iinkcukacha encinane luncedo - metadata. Le nto ishwankathela zonke iinkcukacha ezikhoyo. Kuba leyo eyenzelwe kwaye sebenzisa?

Yintoni layo?

Kufuneka kuqatshelwe ukuba ayisekho imixube omnye kolu luvo. Ngenxa yoko, i-CC - eli ligama eliqhelekileyo iinkcukacha weenkcukacha. Esisetyenziselwa iziqu ezine gama:

1. Elisenokubhekisela ulwazi subchannel malunga data ezisetyenzisiweyo.
2. Ngoko ke ukubiza iimpawu ezichaza uqobo. Kufuneka ukuba sijonge ukuba, ukuchonga, ukuvavanya nokulawula amaxabiso kwiziko ledatha. Ke ngokuba ebalulekileyo iqela elithile zeenkcazo yakhiwe ebonelelwe efanelekileyo nefikelelekayo ngohlobo ecacileyo, ukuze ufumane into oyifunayo. Eli gama lisetyenziswa kwiimeko apho kuyimfuneko khangela ubunjalo, izibonelelo kunye namaziko.
3. Idatha evela kwinkqubo iyonke esesikweni achaza iimpawu yokugcina ethile inkcazelo.
4. Ulwazi malunga iimpawu yekhasi lewebhu (nini, ngubani na wadalwa ngumbhali).

Umahluko phakathi kwe data kunye metadata

Indlela yokwahlukanisa kubo? Isibakala sokuba ukwahlulwa ocacile jikelele akunakwenzeka. Kutheni? Makhe sihlolisise umzekelo:

1. Into senze zombini iindima. Umzekelo, sisihloko senqaku ingabonwa nje into semethadata, njengoko ingcaciso ethunyelwayo kumfundi.
2. Ithuba ukutshintsha iindawo. Masithi umntu wabhala umsebenzi enkondlo. Kuyinto i data. Umqambi, ukuthembela ngamazwi, wadala sisincoko zomculo kunye itekisi iqhotyoshelweyo. Kulo mzekelo, oku iguqulelwa metadata. Yonke kuxhomekeke ekusetyenzisweni. Ngokuqhelekileyo, iimeko ezinjalo kuba ngenxa kwimbono indawo ethile imbono ngenxa yomgwebo yabo (apha idlala indima segama kunye reference system).
3. Ukukwazi ukwenza meta ... -metadannyh egxininisa saziwe oyikhethileyo. Oku kulandela ukusuka yokuba phantse nayiphi na inkqubo lolwazi anokwenziwa iimpawu zalo.

iifayile metadata computer

ukusebenzisa kwabo baza abayifumeneyo de ugqitywe ezenzekelayo. Ukuba inkqubo uyakwazi ukusebenza kunye neziqulatho kunye nolwakhiwo data, ukuba zitshintshwe zibe olunye uhlobo lolwazi evumela ukuba abasebenzisi simahla ukususela ezahlukeneyo izenzo ungakhululekanga kwaye ngokomgaqo. Umzekelo uphuhliso, evumela ukuba ukujonga nemizobo ngezandiso ezahlukeneyo. Unakho ukukhumbula ezahlukeneyo ushicilelo isandi, bhanyabhanya kunye nezinye izinto ezininzi.

Metadata kuthungelwano jikelele

Kwi-Internet kunye nabo yenziwa ukufumana ulwazi oluyimfuneko luncedo phakathi eninzi lwe data. Ukusuka lo mbono, layo ukuba wadala ngesandla, nibagqithile ixabiso elikhulu ngenxa meaningfulness yayo. Njengoko olu hlobo lwazi inokufana ngamagama, egama, kwaye inani nezinye izinto. CC - kukuba ngokufutshane isixelela site. Xa kuhlalutywa iinjini zokuphendla kwiindawo ezimbalwa, ukuba ndibatyhilele amazwi isihloko enye, ngoko reference bathandana omnye kuya kubaluleka ngaphezu sites kunesiqhelo.

ngezigaba metadata

Indlela yokwahlukanisa kubo? Ngokusisiseko, ulwahlulohlulo ikhutshwa phandle ngomnye kwimigaqo emibini:

1. Content. Layo lisetyenziswa ukuchaza ifayile, resource okanye okubhalwe kuyo (umzekelo, isihloko - "ukupheka iitapile").
2. Ngokwe nezincedisi. Layo ingasetyenziswa ukwazisa malunga nento yonke okanye inxalenye. Ngenxa yoko, isihloko lo mfanekiso ushukumayo uthetha zonke kuyo, yaye inkcazelo episode yazisa kuphela ingxenye ethile.

Ukuba CC - iseti izixhomekeki nengqikelelo izakhono, apho kunokwenzeka ukuba zohlulwa ngokwendidi 3:

1. "Raw" data. Imithetho Information Security.
2. Iimpawu echaza umxholo. Nabo ke, nazo kusetyenziswa.
3. Layo ezinokusetyenziswa ukwenza kwisigqibo esisiso.

Ezi ntlobo metadata zikhona.

Ezintathu eklasini abaninzi bafuna emva

Nceda fumana iiklasi ezintathu, ezo zisetyenziswa ngokubanzi:

1. metadata yangaphakathi. Olu lwazi echaza iindawo zecandelo yezinto, ubume babo nento limele. Ngokomzekelo, ubukhulu kunye ifayile format.
2. metadata Administrative. Kufuneka ukuba processing of ulwazi, kwakunye ukuqeshwa yezinto. Umzekelo, ngubani na ke umbhali, umhleli, xa Ifayile ye wav isusiwe.
3. metadata esichazayo. Zisetyenziselwa ukuchaza uhlobo lwefayile kunye neempawu zayo (leyo udidi isebenza yintoni enye enxulumene).

format metadata

Ngoko wabiza umgangatho, ethi isetyenziswe ukwenza inkcazo esesikweni ezinye iindidi kwezibonelelo (ezikhoyo, izinto kunye like).
Ngokuqhelekileyo isiphathele iseti ethile oluphawula into umbuzo. Ukulungiselela le njongo, iimpawu, iimpawu, kunye nezinto metadata.
Zihlelwa ububanzi kunye neenkcukacha kwezibonelelo ezichazwe.

neengxaki

Xa iimpawu kwenzeke impazamo? Ukunqongophala kolwazi okanye ufikelelo kwisithintelo - ezi unobangela iingxaki. Kwakhona, imposiso metadata ukulayisha kwenzeka kwiimeko apho ifayile, kodwa yonakele. Izizathu eziphambili zale meko-akhawunti ezintathu: ukunxiba izixhobo, ifuthe eziyingozi lweenkqubo ngamnye (idla amagciwane) kunye nokugqitywa ngokungafanelekanga yoxwebhu, apho sizathu data alondolozwe kakuhle.

Ngako oko, ixabiso layo kwi ngokuhlelwa systematization kolwazi womnatha ayikwazi nemikhuba. Ngoko ke, enqwenela nokwandisa website yakho kufuna nje ulwazi ngabo.
