Data-Ed: Metadata Strategies

Data-Ed: Metadata Strategies
Metadata Management Strategies Copyright 2014 by Data Blueprint Good systems development often depends on multiple data management disciplines that provide a solid foundation. One of these is metadata. While much of the discussion around metadata focuses on understanding metadata itself along with its associated technologies, this perspective often represents a typical tool-and-technology focus, which has not achieved significant results to date. A more relevant question when considering pockets of metadata is whether to include them in the scope of organizational metadata practices. By understanding what it means to include items in the scope of your metadata practices, you can begin to build systems that allow you to practice sophisticated ways to advance data management and supported business initiatives with a demonstrable ROI. After a bit of practice in this manner you can position your organization to better exploit any and all metadata technologies in support of business strategy.   Date: November 11, 2014 Time: 2:00 PM ET/11:00 AM PT Presenter: Peter Aiken, Ph.D.

Whither the "data dictionary? 6 Copyright 2014 by Data Blueprint • The classic "data dictionary" pretty much died by the early '90s - ... they ever-so-kindly renamed "data dictionary" to "metadata repository" & then promptly went belly up. Ask pretty much IBMer today if they've ever heard of AD/Cycle or RepositoryManager... guaranteed response will be a blank stare. • My calculation says 5% survival rate from 1973 to 2003 • Metadata has morphed into a meaningless buzzword … - Yet organizations are suffering from unprecedented amounts of new forms of seriously unmanaged metadata. • I've essentially given up on trying to grok what metadata is other than "required buzzword" (Dave Eddy/deddy@davideddy.com)

What is a Strategy? 20 Copyright 2014 by Data Blueprint • Current use derived from military • "a pattern in a stream of decisions" [Henry Mintzberg] • "a system of finding, formulating, and developing a doctrine that will ensure long-term success if followed faithfully [Vladimir Kvint]
Meta data, Meta-data, or metadata 21 Copyright 2014 by Data Blueprint • In the history of language, whenever two words are pasted together to form a combined concept initially, a hyphen links them • With the passage of time,   the hyphen is lost. The   argument can be made   that that time has passed • There is a copyright on   the term "metadata," but   it has not been enforced • So, term is "metadata"
Definitions 22 Copyright 2014 by Data Blueprint • Metadata is – Everywhere in every data management activity and integral   to all IT systems and applications. – To data what data is to real life. Data reflects real life transactions, events, objects, relationships, etc. Metadata reflects data transactions, events, objects, relations, etc. – The data that describe the structure and workings of an   organization’s use of information, and which describe the   systems it uses to manage that information.   [quote from David Hay's book, page 4] • Data describing various facets of a data asset, for the purpose of improving its usability throughout its life cycle [Gartner 2010] • Metadata unlocks the value of data, and therefore requires management attention [Gartner 2011] • Metadata Management is – The set of processes that ensure proper creation, storage, integration, and control to support associated use of metadata

Analogy: a library card catalog 24 Copyright 2014 by Data Blueprint • Identifies – What books are in the library, and – Where they are located • Search by – Subject area – Author, or – Title • Catalog shows – Author – Subject tags – Publication date and – Revision history • Determine which books will   meet the reader’s requirements • Without the catalog, finding things is difficult, time consuming and frustrating  from The DAMA Guide to the Data Management Body of Knowledge © 2009 by DAMA International
Definition (continued) 25 Copyright 2014 by Data Blueprint • Metadata is the card catalog in a managed data environment • Abstractly, Metadata is the descriptive tags or context on the data (the content) in a managed data environment • Metadata shows business and technical users where to find information in data repositories • Metadata provides details on where the data came from, how it got there, any transformations, and its level of quality • Metadata provides assistance with what the data really means and how to interpret it from The DAMA Guide to the Data Management Body of Knowledge © 2009 by DAMA International
Defining Metadata 26 Copyright 2014 by Data Blueprint Metadata is any combination of any circle and the data in the center that unlocks the value of the data! Adapted from Brad Melton Data WhereWhy What How Who When Data
Library Metadata Example Libraries can operate efficiently through careful   use of metadata (Card Catalog)    Who: Author What: Title Where: Shelf Location When: Publication Date  A small amount of metadata (Card Catalog) unlocks the value of a large amount of data (the Library) 27 Copyright 2014 by Data Blueprint Data WhereWhy What How Who When Library Book
Outlook Example 28 Copyright 2014 by Data Blueprint "Outlook" metadata is used to navigate/manage email  What: "Subject" How: "Priority" Where: "USERID/Inbox",   "USERID/Personal" Why: "Body" When: "Sent" & "Received”  • Find the important stuff/weed out junk • Organize for future access/outlook rules • Imagine how managing e-mail (already non-trivial) would change if Outlook did not make use of metadata Who:"To" & "From?"
Uses What is the structure of metadata practices? 29 Copyright 2014 by Data Blueprint Sources   Metadata Governance   Metadata Engineering   Metadata Delivery Metadata Practices Metadata  Storage Specialized Team Skills • Metadata practices connect data sources and uses in an organized and efficient manner – Storage: repository, glossary, models, lineage - often multiple  technologies – Engineering: identifying/harvesting/normalizing/administer   evolving metadata structures – Delivery: supply/access/portal/definition/lookup search   identify/ensure required metadata supplies to   meet business needs – Governance: ensure proper/creation/storage/integration/control   to support effective use • When executed, engineering and delivery implement governance

7 Metadata Benefits 44 Copyright 2014 by Data Blueprint 1. Increase the value of strategic information (e.g. data warehousing, CRM, SCM, etc.) by providing context for the data, thus aiding analysts in making more effective decisions. 2. Reduce training costs and lower the impact of staff turnover through thorough documentation of data context, history, and origin. 3. Reduce data-oriented research time by assisting business analysts in finding the information they need in a timely manner. 4. Improve communication by bridging the gap between business users and IT professionals, leveraging work done by other teams and increasing confidence in IT system data. 5. Increased speed of system development’s time-to-market by reducing system development life-cycle time. 6. Reduce risk of project failure through better impact analysis at various levels during change management. 7. Identify and reduce redundant data and processes, thereby reducing rework and use of redundant, out-of-data, or incorrect data. from The DAMA Guide to the Data Management Body of Knowledge © 2009 by DAMA International
Metadata for Semistructured Data 45 Copyright 2014 by Data Blueprint • Unstructured data – Any data that is not in a database or data file, including documents or other media data • Metadata describes both structured and unstructured data • Metadata for unstructured data exists in many formats, responding to a variety of different requirements • Examples of Metadata repositories describing unstructured data: – Content management applications – University websites – Company intranet sites – Data archives – Electronic journals collections – Community resource lists • Common method for classifying Metadata in unstructured sources is to describe them as descriptive metadata, structural metadata, or administrative metadata from The DAMA Guide to the Data Management Body of Knowledge © 2009 by DAMA International
Metadata for Unstructured Data: Examples 46 Copyright 2014 by Data Blueprint • Examples of descriptive metadata: – Catalog information – Thesauri keyword terms • Examples of structural metadata – Dublin Core – Field structures – Format (audio/visual, booklet) – Thesauri keyword labels – XML schemas • Examples of administrative metadata – Source(s) – Integration/update schedule – Access rights – Page relationships (e.g. site navigational design)
Specific Example 47 Copyright 2014 by Data Blueprint • Four metadata sources: 1. Existing reference models (i.e., ADRM) 2. Conceptual model created two years ago 3. Existing systems (to be reverse engineered) 4. Enterprise data model } from The DAMA Guide to the Data Management Body of Knowledge © 2009 by DAMA International
Metadata History 1990-2008 50 Copyright 2014 by Data Blueprint • The history of Metadata management tools and products seems to be a metaphor for the lack of a methodological approach to enterprise information management: • Lack of standards and proprietary nature of most managed Metadata solutions cause many organizations to avoid focusing on metadata • This limits organizations’ ability to develop a true enterprise information management environment • Increased attention given to information and its importance to an organization’s operations and decision-making will drive Metadata management products and solutions to become more standardized • More recognition to the need for a methodological approach to managing information and metadata
Metadata History: The 1990s 51 Copyright 2014 by Data Blueprint • Business managers began to recognize the value of Metadata repositories • Newer tools expanded the scope • Potential benefits identified during this period include: – Providing semantic layer between company’s system and business users – Reducing training costs – Making strategic information more valuable as aid in decision making – Creating actionable information – Limiting incorrect decisions
Metadata History: Mid-to late 1990s 52 Copyright 2014 by Data Blueprint • Metadata becomes more relevant to corporations who were struggling to understand their information resources caused by: – Y2K deadline – Emerging data warehousing initiatives – Growing focus around the World Wide Web • Beginning of efforts to try to standardize Metadata definition and exchange between applications in the enterprise • Examples of standardization: – 1995: CASE Definition Interchange Facility (CDIF) – 1995: Dublin Core Metadata Elements – 1994 – 1999: First parts of ISO 11179 standard for Specification and Standardization of Data Elements were published – 1998: Common Warehouse Metadata Model (CWM) – 1995: Metadata Coalitions’ (MDC) Open Information Model – 2000: Both standards merged into CSM. Many Metadata repositories began promising adoption of CWM standard
Metadata History: 21st Century 53 Copyright 2014 by Data Blueprint • Update of existing Metadata repositories for deployment on the web • Introduction of products to support CWM • Vendors begin focusing on Metadata as an additional product offering • Few organizations purchase or develop Metadata repositories • Effective enterprise-wide Managed Metadata Environments are rare due to: – Scarcity of people with real world skills – Difficulty of the effort – Less than stellar success of some of the initial efforts at some companies – Stagnation of the tool market after the initial burst of interest in late 90s – Still less than universal understanding of the business benefits – Too heavy emphasis on legacy applications and technical metadata
Metadata History: Current Decade 54 Copyright 2014 by Data Blueprint • Focus on need for and importance of metadata • Focus on how to incorporate Metadata beyond traditional structured sources and include semistructured sources • Driving factors: – Recent entry of larger vendors into the market – Challenges related to addressing regulatory requirements, e.g. Sarbanes-Oxley, and privacy requirements with unsophisticated tools – Emergence of enterprise-wide initiatives, e.g. information governance, compliance, enterprise architecture, automated software reuse – Improvements to the existing Metadata standards, e.g. RFP release of new OMG standard Information Management Metamodel (IMM), which will replace CWM – Recognition at the highest levels that information is an asset that must be actively and effectively managed
Why Metadata Matters 55 Copyright 2014 by Data Blueprint • They know you rang a phone sex service at 2:24 am and spoke for 18 minutes. But they don't know what you talked about. • They know you called the suicide prevention hotline from the Golden Gate Bridge. But the topic of the call remains a secret. • They know you spoke with an HIV testing service, then your doctor, then your health insurance company in the same hour. But they don't know what was discussed. • They know you received a call from the local NRA office while it was having a campaign against gun legislation, and then called your senators and congressional representatives immediately after. But the content of those calls remains safe from government intrusion. • They know you called a gynecologist, spoke for a half hour, and then called the local Planned Parenthood's number later that day. But nobody knows what you spoke about. – https://www.eff.org/deeplinks/2013/06/why-metadata-matters
Metadata Strategy 56 Copyright 2014 by Data Blueprint • Metadata Strategy is – A statement of direction in Metadata management by the enterprise – A statement of intend that acts as a reference framework for the development teams – Driven by business objectives and prioritized by the business value they bring to the organization • Build a Metadata strategy from a set of defined components • Primary focus of Metadata strategy – gain an understanding of and consensus on the organization’s key business drivers, issues, and information requirements for the enterprise Metadata program • Need to understand how well the current environment meets these requirements now and in the future • Metadata strategy objectives define the organization’s future enterprise metadata architecture and recommend logical progression of phased implementation steps • Only 1 in 10 organizations has a documented, board approved data strategy
