Much video data is delivered within container formats like AVI, MPEG-4, Flash, or Ogg, and these containers often provide embedded metadata support.

Nichols, in How to Build a Digital Library (Second Edition), 2010 Video metadata When examining office documents that may be of questionable veracity, the existence of printer make and model can be used to create a timeframe in which the document must have been printed.

The release date of this version of the software used to generate the document is the earliest date that the file could have existed.

As an example, many PDF files will contain the name and version of the software used to generate them. They can retain their time information for recovery after deletion, even when the file system metadata structures have been removed.ДЇile content may contain another source of time information as well: embedded inferred time. Embedded times can travel within the files as they move from system to system and cannot be manipulated directly with the same tools used to manipulate file system time data. The fact that they contain time information is frequently overlooked by or unknown to the actors that generate or transmit them. Like information from devices external to the system, these time artifacts can be a very rich source of temporal data. We discussed the extraction of time information from file metadata in Chapter 8.

Once the metadata columns have been populated, you can query the metadata to find, or find out about, the LOB data вЂ“ e.g., think of the movie example as metadata for the actual movie.Д¬ory Altheide, Harlan Carvey, in Digital Forensics with Open Source Tools, 2011 Embedded Times At the time of writing, this technology вЂ“ automatic entity extraction вЂ“ is still in its infancy.

They work by recognizing names of people and companies and so on and possibly checking those names against an internal dictionary or a web service. Some interesting program 13 can produce meaningful metadata for text documents automatically, even when that metadata does not exist explicitly in the document. A CMS (content management system) will allow the publisher to add all kinds of metadata at various stages of the publishing process. Whoever publishes the data вЂ“ inserts the data into a database вЂ“ can add metadata via an application. But the LOB is still opaque вЂ“ some processing needs to be done to вЂњdecorateвЂќ it with metadata, even if that metadata exists in the LOB. For example, Oracle's inter Media product will extract metadata from most common document, audio, video, and image formats and make that metadata available for query in columns of a table. This metadata can be extracted programmatically and written into database columns as the data is inserted. вЂ“ and some metadata that can be added by the author. Text formats (PDF, Microsoft Word) generally contain some automatically generated metadata вЂ“ the author's name, document title, last modified date, etc. Some formats have metadata embedded in them. There are several ways to create the metadata: Then we can query the metadata to find a particular instance of a LOB or to find out information about an instance of a LOB.

Once we have the data in a LOB, we can store it in a database table and add metadata in other columns in the table. But the data is opaque i.e., nothing is known about a LOB instance except that it may be large. A LOB is handled in a special way by the database to cope with its potentially large size вЂ“ typically two or four gigabytes. A binary LOB is a LOB that contains data that is not character-based, as opposed to a character LOB, or CLOB, which contains data that is in the character set of the database. LOB storage just means that the data item is stored as a single item in one place. Despite its name, a LOB has none of the useful attributes of an object. In a database this opaque chunk is often called a BLOB, or binary large object.

One approach is to store the nontraditional data as an opaque chunk of data and add metadata. Jim Melton, Stephen Buxton, in Querying XML, 2006 2.3.1 Metadata
