Tim Berners-Lee a anun\u021bat decizia de a conferi specifica\u021biei care define\u0219te identificatoarele descentralizate pentru Web (DID, Decentralized Identifier) statutul de standard recomandat. Obiec\u021biile formulate de companiile Google \u0219i Mozilla au fost respinse. <\/p>\n

Specificarea DID introduce un nou tip de identificatori globali unici, care nu sunt lega\u021bi de servicii \u0219i organiza\u021bii centralizate, cum ar fi registratorii de domenii \u0219i autorit\u0103\u021bile de certificare. Un identificator poate fi asociat cu orice resurs\u0103 \u0219i generat prin sisteme de \u00eencredere pentru proprietarul resursei. Pentru a verifica autenticitatea identificatorului, se folose\u0219te autentificarea bazat\u0103 pe dovada de\u021bin\u0103torului, utiliz\u00e2nd mecanisme criptografice, cum ar fi semn\u0103turile digitale. Specifica\u021bia permite utilizarea diverselor metode de gestionare distribuit\u0103 \u0219i de ob\u021binere a informa\u021biilor despre identificatori, inclusiv metode bazate pe blockchain. <\/p>\n

Noul format URI este structurat ca \u201edid:metod\u0103:identificator_unic\u201d, unde \u201edid\u201d define\u0219te o nou\u0103 schem\u0103 URI, \u201emetod\u0103\u201d indic\u0103 mecanismul de procesare a identificatorului, iar \u201eidentificator_unic\u201d reprezint\u0103 un identificator specific metodei alese, de exemplu, \u201edid:example:123456789abcdefghi\u201d. \u00cen c\u00e2mpul metodei se specific\u0103 numele serviciului de stocare a datelor verificate, care garanteaz\u0103 unicitatea identificatorului, definind formatul acestuia \u0219i asigur\u00e2nd leg\u0103tura identificatorului cu resursa pentru care a fost creat. URI-ul cu identificatorul este transformat \u00eentr-un document \u00een format JSON, cu metadate care descriu obiectul solicitat \u0219i includ chei publice pentru verificarea proprietarului.

\"Identificatorii<\/center> <\/p>\n

Implement\u0103rile metodelor dep\u0103\u0219esc standardul DID, fiind definite \u00een specifica\u021biile lor \u0219i sus\u021binute \u00eentr-un registru separat. \u00cen prezent, sunt propuse 135 de metode bazate pe diverse blockchain-uri, algoritmi cryptografici, tehnologii distribuite, baze de date decentralizate, sisteme P2P \u0219i mecanisme de identificare. De asemenea, este permis\u0103 crearea unor straturi DID deasupra sistemelor centralizate; de exemplu, metoda web permite leg\u0103tura cu nume tradi\u021bionale de gazde (de exemplu, \u201edid:web:example.com\u201d). <\/p>\n

Obiec\u021biile Google se refer\u0103 la separarea specifica\u021biei mecanismului general al identificatorilor descentraliza\u021bi de specifica\u021biile implement\u0103rilor metodologice, ceea ce nu permite analiza validit\u0103\u021bii specifica\u021biei principale f\u0103r\u0103 a studia specifica\u021biile metodologice. Publicarea specifica\u021biei principale f\u0103r\u0103 preg\u0103tirea specifica\u021biilor metodologice \u00eengreuneaz\u0103 revizuirea, iar Google a sugerat am\u00e2narea standardiz\u0103rii specifica\u021biei generale DID p\u00e2n\u0103 c\u00e2nd mai multe metode de top vor fi preg\u0103tite pentru standardizare, deoarece \u00een procesul de standardizare a metodelor pot ap\u0103rea aspecte subtile ce necesit\u0103 o retratare a specifica\u021biei principale. <\/p>\n

Obiec\u021biile Mozilla se refer\u0103 la faptul c\u0103 specifica\u021bia nu \u00eencurajeaz\u0103 adecvat asigurarea portabilit\u0103\u021bii, l\u0103s\u00e2nd aceast\u0103 \u00eentrebare pe seama registrului metodologic. \u00cenregistrul con\u021bine deja peste o sut\u0103 de metode, create f\u0103r\u0103 a lua \u00een considerare compatibilitatea \u0219i unificarea solu\u021biilor standard. \u00cen forma sa actual\u0103, se \u00eencurajeaz\u0103 crearea unei noi metode pentru fiecare sarcin\u0103, \u00een loc s\u0103 se \u00eencerce adaptarea metodelor existente la propriile nevoi. <\/p>\n

Pozi\u021bia W3C se rezum\u0103 la faptul c\u0103 standardizarea specifica\u021biei DID, care define\u0219te o nou\u0103 clas\u0103 extensibil\u0103 de identificatori \u0219i sintaxa asociat\u0103, va stimula dezvoltarea metodelor \u0219i va ajuta la atingerea unui consens \u00een leg\u0103tur\u0103 cu standardizarea acestora. \u00cen forma actual\u0103 exist\u0103 suficiente dovezi ale aplicabilit\u0103\u021bii specifica\u021biei principale pentru a solu\u021biona problemele solicitate de comunitatea care dezvolt\u0103 tehnologiile descentralizate. Implement\u0103rile propuse ale metodelor nu ar trebui evaluate prin analogie cu noile scheme URL, iar crearea unui num\u0103r mare de metode poate fi considerat\u0103 ca o coresponden\u021b\u0103 a specifica\u021biei de baz\u0103 cu nevoile dezvoltatorilor. <\/p>\n

Standardizarea anumitor metode este considerat\u0103 o sarcin\u0103 mai complex\u0103, din perspectiva atingerii consensului \u00een r\u00e2ndul dezvoltatorilor, dec\u00e2t standardizarea clasei generale de identificatori. Prin urmare, aprobarea specifica\u021biei generale \u00eenainte de standardizarea metodelor este v\u0103zut\u0103 ca o solu\u021bie capabil\u0103 s\u0103 provoace un poten\u021bial prejudiciu mai mic pentru comunitatea care implementeaz\u0103 identificatori descentraliza\u021bi.
