Why is metadata important?
Metadata is “data about data,” or information used to classify other information.2 Metadata has played an important role in library and computer sciences because it allows for knowledge management , for example, in the case of books, enabling a useful classification according to such metadata as author, title, date of a publication, as well as publisher, size, number of pages, and genre. In a library catalog, metadata allows patrons to locate books they were expressly seeking or to discover books of potential interest about which they may not have previously known. Beyond books, metadata also plays
What is contextual integrity?
According to the theory of contextual integrity, the appropriateness of a particular information flow depends not only on the type of information in question (the attribute) but also on the actors involved (senders, subjects and recipients of an information type) and the transmission principles (constraints on flow). If a practice generates changes in any of these three parameters, a prima facie case exists for claiming that contextual integrity, and hence privacy, has been violated.52 This prima facie assessment does not necessarily mean, however, that the new practice needs to be abandoned. Indeed, if the new practice better promotes the values, goals and ends of a given context, then contextual integrity allows for and even encourages alterations in information flows.53 Material advances in the science and technology of data along with institutional practices have dramatically altered the social and technological environment in which metadata is generated and
Do we share metadata?
Often, we do not share metadata voluntarily. Furthermore, technological innovations in aggregation, storage, combination and analysis increase the ability of those with whom we share our data to extract useful information from that data. But beyond that, changes in the social, technological and legal environment have made previously hard to obtain metadata easily accessible so that we effectively assume the risk of surveillance whenever we communicate. The extension of the doctrine of misplaced trust from people to businesses is a telling case. Of course, nobody can protect us against sharing personal information with a friend who turns out to be not that great of a friend or, in particular instances, an undercover police agent.90 When we share intimate information with others we indeed assume the risk that those with whom we share our data will be untrustworthy. However, the nature of the information sharing changes radically when the recipients of an information flow are no longer people but businesses, e.g. banks, telephone and web service providers, and hospitals. The question here is no longer about the terms of a friendship but the terms of a transaction. Of course, the Supreme Court ruled in United States v. Miller that
Why is metadata important?
Additionally, metadata are essential for bridging programs and databases because they provide the framework for data exchange and communication within and between organizations. Metadata also inform data policymaking (for example, data retention procedures) and technology planning (such as load time demands) throughout an organization.
Can you argue with the data?
You can't argue with the data A false sense of security may arise when data are used improperly. Decisions based on misunderstood data can be disastrous. In fact, data without metadata can have consequences far worse than having no data at all.
Why is metadata management important?

What is metadata in computer?
Metadata can be a veritable gold mine of useful information in a case. The prefix meta in English is used to express the idea that some information is about its own category. Hence the meaning of metadata is “data about data,” just as metacognition means “knowing about knowing.” While this might seem somewhat cryptic, when you get down to the nuts and bolts, metadata is not hard to understand in principle, but can be confusing in detail. Metadata can be found inside a file, kind of behind the scenes where an ordinary computer user will not see it, or in an external data store such as Internet history files that record information about files.
Why use MODS in digitization?
As Dulock (2012) describes, MODS is used for descriptive metadata in digitization projects because of its ample metadata element set. However, MODS metadata needs to be mapped to Dublin Core for harvesting purposes because of the requirements of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) ( Dulock, 2012 ).
What is MAT in Python?
MAT or metadata anonymization toolkit is a graphical user interface tool which also helps to remove metadata from different types of files. It is developed in Python and utilizes hachoir library for the purpose. As earlier we discussed a bit about hachoir Python library and one of its project in hachoir-metadata portion, this is another project based on the same library. The details regarding the same can be found here https://mat.boum.org/.

Why is metadata important in BI?
The existence of disparate data systems that contribute information to the BI environment complicates this process, because each system may have its own methods for managing its own metadata. Yet ultimately the metadata analysts will need to formalize practices and procedures for soliciting information from the different system owners and consolidating that knowledge within the capabilities of existing frameworks.
How does metadata help forensic investigators?
Metadata is often incredibly useful to a forensic investigator, helping to establish the “who, what, where and how” of computer-based activity. But metadata is also easy to misinterpret—or just miss altogether. This chapter explores some of the risks associated with analyzing metadata and the challenges of drawing reliable conclusions from such analysis. This chapter will focus on defining some of the specific issues encountered when analyzing Microsoft Office metadata, the most common file types forensic investigators encounter. Not only can metadata be altered intentionally to throw off an investigator, but the Microsoft rules that govern how and when metadata is created and updated over time can generate some puzzling and even inexplicable results. After reviewing the types of information that may be obtained from Office metadata, the Chapter will use some specific examples and factual scenarios to demonstrate the intricacies, twists and turns encountered in the process of extracting and interpreting metadata. By gaining insight from an experienced forensic examiner, the reader will learn how to avoid some of the pitfalls of metadata analysis that can lead to misinterpretation of seemingly reliable metadata.
