Frank 4 Evolution of Metadata PLALDL Web & XML Technology Content descriptio n File transfer protocols Description of content & presentation … & meaning Evolution of Metadata Different communities – of both users and practitioners Different levels of interaction and of interoperability

H. Weinberger - A. Frank 5 Introduction to Metadata 1. Metadata definition 2. What is metadata? 3. Why metadata? 4. Dimensions of metadata & development approaches 5. Categories of metadata

H. Weinberger - A. Frank 6 Metadata is ” Data about Data" - Descriptions of what kind of information resource is stored where, how it is encoded, how it is related to other information and where it comes from. Metadata is machine understandable information for the web Metadata Definition

H. Weinberger - A. Frank 7 2. What is Metadata? Metadata is data: what, where, how. Ex: Where can I find what is there? How to define it? Structured data about data: templates. Ex: TL, SH, AU, WO - in Aleph. Machine understandable information about resources: standards, protocols, etc. Ex: HTTP, z39, XML. Metadata can describe data, information, knowledge. Ex: URL, URN.

H. Weinberger - A. Frank 8 3. Why Metadata? על מנת לאפשר תוצאות טובות יותר באחזור מידע. על מנת לתמוך ביכולת של מנועי חיפוש. כדי לקיים תפעוליות-בינית בין מערכות מידע. כדי לאפשר שיתוף במשאבים בין ארגונים ובין קבוצות.

H. Weinberger - A. Frank 9 4. Dimensions of Metadata & Development Approaches 1. Resource dimension – origin: Bibliographic control approach – Structural Metadata: fields of description. – Metadata Key: for managing the object in networked environment. 2. System dimension – origin: Data management approach – Enabling Technologies: infrastructure for information retrieval, search & access information. – Standards: used for Semantic & Syntactic Interoperability to bridge over communities of users.

H. Weinberger - A. Frank Resource Dimension Metadata & Information Resource Discovery Discovery and description of Web resources are facilitated by the use of metadata: – Supports Information Retrieval (IR). – Enhances SEs & Web crawlers capabilities. Self-descriptive information that Web authors can embed directly in their documents.

H. Weinberger - A. Frank System Dimension Metadata & Information Resource Discovery Discovery and description of Web resources are facilitated by the use of metadata: – Supports Information Retrieval (IR). – Enhances SEs & Web crawlers capabilities. Self-descriptive information that Web authors can embed directly in their documents.

H. Weinberger - A. Frank Categories of Metadata 1.Descriptive Systems 2.Structural Systems 3.Administrative Metadata

H. Weinberger - A. Frank Descriptive Metadata שיטות מידע-על שמתארות אובייקט – שם נוסף: Knowledge Organization Systems דוגמאות (על ציר הזמן, הפריסה היא על כל סוגי הספריות): – ערך בקטלוג (Catalog Entry) – תקצירים (Abstracts) – רשומות מפתוח (Indexing records) דוגמאות ליישומים: AACR, MARC, MESH, THESAURI, DC מידע-על תיאורי: – מאוחסן בנפרד מהאובייקט – בדר"כ טקסטים – יכולת תאור פרטים שאינם בטקסט

H. Weinberger - A. Frank Structural Metadata אלמנטים מבניים Structural elements: – ( מבנה קיים ) גוף המסמך, פסקה, כותרות, רשימה צורת המסמך Document Appearance: – ( תאור הופעה ) גופן מודגש, מוטה וכיוצ " ב – טקסט ממורכז, מיושר לימין וכיוצ " ב דוגמאות ליישומים : – שפות סימון Mark-up languages – מסגרות לייצוג מסמכים מיצוב אובייקטים : – מיקום תמונה, וכיוצ " ב

H. Weinberger - A. Frank Administrative Metadata זכויות יוצרים : – מדיניות וכללים בנושאי שימוש והפצה של המידע. מדיניות והעדפות בנושאי פרטיות : – יחס המשתמש לגלוי פרטיו. – האתר : רצון האתר לאיסוף מידע על משתמשים.

H. Weinberger - A. Frank 16 Contents of Metadata Lecture 1. Introduction to Metadata 2. Interoperability of Metadata 3. Evolution of Descriptive Metadata 4. Web Descriptive Metadata 5. Structured Metadata 6. Semantic Web

H. Weinberger - A. Frank 17 Interoperability 1. הגדרה של תפעוליות - בינית 2. תפעוליות - בינית בספריה דיגיטלית 3. היבטים של תפעוליות - בינית 4. רמות של תפעוליות - בינית 5. יתרונות 6. דוגמאות : יישומים של מידע - על 7. תפעוליות - בינית ומידע - על 8. מבט לעתיד : Semantic Web

H. Weinberger - A. Frank Definition תפעוליות - בינית היכולת לאפשר למערכות שונות ומבוזרות לעבוד יחד. תפעוליות - בינית מתייחסת למנעד רחב של היבטים.

H. Weinberger - A. Frank 19 IRD in practice

H. Weinberger - A. Frank Needs in DL אילו סוגים של תפעוליות - בינית נחוצים ? – טכנולוגיים, מתן שירותים : בין ספריות, בין מערכות, בין מסמכים, ועוד. איזו מסגרת עבודה דרושה כדי להשיגם ? – שיתופיות, תקנים מורכבות, היבטים ובעיות : – טכנולוגיות מידע : רשתות, מסדי ידע, מערכות מחשב, אחזור מידע – שירותים : יכולת דפדוף בין אוספים, חיפוש, עיצוב מחדש של מסמכים, זכויות יוצרים, הרשאות שימוש. – המידע : מגוון וסוגים

H. Weinberger - A. Frank Dimensions of Interoperability (1) מנשק אנוש-מחשב (HCI) : חתירה לגיבוש דפוס תצוגה עקבי. שמות וזיהוי (Naming and Identification): דרוש תקן לזיהוי משאבים באופן בלתי תלוי במיקום. פורמט (Format) : גיבוש הסכמות לגבי מערכות סימנים לעיצוב טקסטים ותמונות (בנוסף ל- HTML, JPEG). מידע-על (Metadata): הצורך בהשגת האחדה לגבי שמות של שדות מידע-על, פורמט קידוד ומשמעות.

H. Weinberger - A. Frank Dimensions of Interoperability (2) חיפוש מידע מבוזר (Distributed searching) – הצורך בהאחדת דפוסי תיאור של משאבים. ניהול רשתות מחשבים (Network protocols) – מעבר לפרוטוקול האינטרנט, לצורכי אודיו ווידאו לדוגמא. פרוטוקולים להעברת מידע (Retrieval protocols) – פרוטוקולים שיתמכו בפעולות חיפוש שונות. זיהוי משתמשים ואבטחת מידע (Authentication and Security) משמעות מסרים בהודעות המוחלפות בין מחשבים (Semantic interoperability)

H. Weinberger - A. Frank Layers of metadata, or: How is metadata shared? – Metadata as language; metadata records as sets of statements. – Effective transmission of information requires agreement on: semantics – what terms mean – e.g., “cat”, “to sit”, “mat” structure – significance of arrangement of terms – e.g., sentence: subject -> verb -> object (in English….) syntax – rules of expression – “The cat sat on the mat.”

H. Weinberger - A. Frank Layers of Interoperability Layers of interoperability architecture: 1. Syntax: Formats, Protocols & Templates 2. Common Tools: Enabling search, Navigation & retrieval 3. Semantics: Tables, Indices, Cataloging rules

H. Weinberger - A. Frank Advantages Communicating data between applications: Benefits – Transparent management of different applications and software. Integrate wide range of information services in a distributed and heterogeneous network environment. Resource discovery application – Transparent searching of and retrieval of data from diverse systems and in different metadata formats.

H. Weinberger - A. Frank Examples (1) Interoperability in practice: – Sharing information between applications regardless of format, standard or protocol. Examples: Z39.50, MARC, Dublin Core, Roads, RDF Supporting Interoperability architecture at 3 levels: 1. Syntax: Formats, Protocols & Templates 2. Common Tools: Enabling search, Navigation & retrieval 3. Semantics: Tables, Indices, Cataloging rules

H. Weinberger - A. Frank Examples (2) 1.MARC 2.Z39.50 from the Library of congress (Structural) 3.Dublin Core (Descriptive) 4.ROADS (Descriptive) 5.RDF (Structural)

H. Weinberger - A. Frank Interoperability in DL Interoperability features of Metadata in DL: Elements description: The Dublin Core Documentation element description. Resource Description Framework : RDF Metadata framework: interoperability between applications. Protocols: Z39.50 interchange protocol Structured Markup Languages: SGML, HTML, XML

H. Weinberger - A. Frank Semantic Interoperability Transparent management of different application software. Transparent searching of and retrieval of data from diverse systems and in metadata formats. Equivalent fields in databases and in indices.
