In terms of information technology, metadata includes the documentation of data architecture, properties, and methods necessary to store, retrieve, and use the data in a meaningful manner. To the extent that data is a record, it may also include administrative, descriptive, preservation, and structural information.
†26 (Bergeron 2002, p. 9): Metadata includes descriptive summaries and highlevel categorization of data and information. Knowledge is information that is organized, synthesized, or summarized to enhance comprehension, awareness, or understanding. That is, knowledge is a combination and an awareness of the context in which the data can be successfully applied. Although the concept of data is roughly equivalent to metadata, unlike data, information, or metadata, knowledge implies a human – rather than computer – host.
†92 (Future 1999): Having heard someone once define information science as ‘librarianship practiced by men,’ Mr. Gorman concluded by defining metadata as ‘cataloging practiced by ill-informed men.’
†175 (C Lynch 2000, p. 34): We have an object and a collection of assertions about it. The assertions may be internal, as in a claim of authorship or date and place of publication on the title page of a book, or external, represented in metadata that accompany the object, perhaps provided by third parties. We want to ask questions about the integrity of the object: Has the object been changed since its creation, and, if so, has this altered the fundamental essence of the object? (This can include asking these questions about accompanying assertions, either embedded in the object or embodied in accompanying metadata).
†223 (Personal communication, Ken Thibodeau, 19 May 2003): Metadata used to have a perfectly nice meaning in engineering, and information technologists’ appropriation of the term ‘ontology’ was payback for librarians’ corruption of ‘metadata’.
†235 (Puglia, Reed, and Rhodes 2004, p. 6): Metadata makes possible several key functions – the identification, management, access, use, and preservation of a digital resource – and is therefore directly associated with most of the steps in a digital imaging project workflow: file naming, capture, processing, quality control, production tracking, search and retrieval design, storage, and long-term management

Axborot texnologiyalari nuqtai nazaridan, metadata ma'lumotlar arxitekturasi, xususiyatlari va ma'lumotlarni mazmunli tarzda saqlash, olish va ulardan foydalanish uchun zarur bo'lgan usullarning hujjatlarini o'z ichiga oladi. Ma'lumotlar yozuv bo'lgan darajada, u ma'muriy, tavsiflovchi, saqlovchi va tizimli ma'lumotlarni ham o'z ichiga olishi mumkin.
†26 (Bergeron 2002, 9-bet): Metadata tavsiflovchi xulosalar va ma'lumotlar va ma'lumotlarning yuqori darajadagi tasnifini o'z ichiga oladi. Bilim - bu tushunish, xabardorlik yoki tushunishni kuchaytirish uchun tashkil etilgan, sintez qilingan yoki umumlashtirilgan ma'lumotdir. Ya'ni, bilim - bu ma'lumotlar muvaffaqiyatli qo'llanilishi mumkin bo'lgan kontekstning kombinatsiyasi va xabardorligi. Ma'lumotlar tushunchasi metama'lumotlarga taxminan ekvivalent bo'lsa-da, ma'lumotlar, ma'lumotlar yoki metama'lumotlardan farqli o'laroq, bilim kompyuter emas, balki insonni anglatadi.
†92 (Kelajak 1999): Bir vaqtlar kimdir axborot fanini shunday ta'riflaganini eshitgan "Kutubxonachilik erkaklar tomonidan qo'llaniladi", deb yakunladi janob Gorman metama'lumotlarni shunday ta'riflash 'kataloglashtirish yomon ma'lumotli odamlar tomonidan amalga oshiriladi'.
†175 (C Lynch 2000, 34-bet): Bizda ob'ekt va u haqida da'volar to'plami mavjud. Ta'kidlar mualliflik da'vosida yoki kitobning sarlavha sahifasida nashr etilgan sana va joy yoki tashqi, ob'ektga hamroh bo'lgan metama'lumotlarda aks ettirilgan, ehtimol uchinchi shaxslar tomonidan taqdim etilgan bo'lishi mumkin. Biz ob'ektning yaxlitligi haqida savollar bermoqchimiz: ob'ekt yaratilganidan beri o'zgarganmi va agar shunday bo'lsa, bu ob'ektning asosiy mohiyatini o'zgartirdimi? (Bu ob'ektga kiritilgan yoki qo'shilgan metama'lumotlarga qo'shilgan tasdiqlar haqida ushbu savollarni berishni o'z ichiga olishi mumkin).
+223 (Shaxsiy aloqa, Ken Thibodeau, 19 may 2003 yil): Metadata ilgari muhandislikda juda yaxshi ma'noga ega edi va axborot texnologlarining "ontologiya" atamasini o'zlashtirgani kutubxonachilarning metama'lumotlarning buzilishi uchun to'lov edi.
†235 (Puglia, Reed, and Rhodes, 2004, 6-bet): Metadata bir nechta asosiy funktsiyalarni - identifikatsiya qilish, boshqarish, kirish, raqamli resursdan foydalanish va saqlashni amalga oshirishga imkon beradi va shuning uchun ularning aksariyati bilan bevosita bog'liqdir. Raqamli tasvirlash loyihasining ish oqimidagi qadamlar: fayl nomini belgilash, yozib olish, qayta ishlash, sifat nazorati, ishlab chiqarishni kuzatish, qidirish va qidirishni loyihalash, saqlash va uzoq muddatli boshqaruv.
