|Machine Readable - Input in a format that the computer can read, such as bar codes that are scanned
directly into the system to be used in an application. Also refers to the binary
information stored onto magnetic media that the computer can access and read into the
Mailbox - 1) Area designated on a network system into which electronic mail messages are stored on disk. Each user has his or her own private mailbox area. 2) Storage facility within an EDI network service set aside for a specific user to hold that user's messages
Mandatory (M) - A statement in a dictionary, segment directory or message directory which specifies that a segment, a data element, a composite data element or a component data element must be used. [ISO 9735]
Mapping - a/k/a Translation, Data Transformation, Conversion, Parsing. The process of translating data from one format to another, using mapping software. Mapping translates proprietary formats to standard formats and vice-versa, or translates one standard format to another standard format.
Mapping Software - a/k/a Translation Software. Computer program or set of programs that transform data from one format to another. Mapping software handles the mapping of a message's business contents (the parts of the message contained inside the envelope). The mapping software may handle the enveloping, but typically does not. c.f. Communications Software, Gateway, Pass-thru, Translator.
Material Requirements Planning (MRP) - Methods and systems designed to determine what materials will be needed over a specified time horizon, and when they will be needed. Demand for a product, in the form of a Master Production Schedule, and planning parameters for components, such as order lead times, is used to "explode" the Bill of Materials into a gross requirements, and then net out available inventory and inventory on order in order to determine what else needs to be procured or fabricated. MRP also looks at open orders - anticipated available inventory - to determine if any rescheduling is recommended. MRPII is next step, and integrates capacity planning and shop floor control, and Enterprise Resource Planning (ERP) is the next generation planning tool.
Maximum use - Specifies the maximum number of occurrences allowed for a data element, composite data element, segment or a loop which maybe repeated.
mCommerce - Was used to desribe manual commerce, but often used now to describe mobile commerce, such as via a mobile phone or PDA.
Mean Time Between Failures (MTBF) - Average amount of time, usually described in thousands or tens of thousands of hours, that elapses before a hardware component fails to the point of requiring ser vice.
Media (plural form of Medium) - Physical material, such as paper, disks, and tapes, used to store computer- related information.
Meet Competition Quote - Used to designate a meet competitor pricing ("meet comp") or delivery quote. This quote is the more complex of the quote types. A meet comp quote is used by the buyer to inquire to a supplier if he/she is willing to lower his/her price, or make a delivery to make a sale. This is used primarily between a distributor and a supplier. The distributor is asking the supplier to lower its price in-line with another supplier of a comparable product to make the sale. This may be after the product has already been shipped to the distributor. This is more complex because of the transaction interaction that is described in Implementation Recommendations for Quote Processes. It may require information about who is the competition, what is their price, and how can their price be verified. The special authorized price is also called an "off book price". See also Ship-from-Stock and Debit.
Message - Unit of information in a communications environment that is transmitted electronically from one device to another; transmission. There are several connotations of the term.
Message Code - In EDIFACT, a unique six character alphabetic reference identifying a message type, e.g. ORDERS for Purchase Order.
Message Diagram - A graphic representation of the hierarchy and sequence of segments or records within a message.
Message Directory - A listing of identified, named, described and specified message types. (EDMD, TRMD)
Message Header - 1) Sequence of bits or bytes at the beginning of a message that usually provides a timing sequence and specifies such aspects pertaining to the message structure as its length, data format, and block identification number. 2) Service segment starting and uniquely identifying a message. [ISO 9735]
Message Status - A formal status given to UN/EDIFACT standard messages by the UN/ECE/WP.4. During UN/EDIFACT standards development, messages and standards are progressed through various stages of development and granted various status. See Status 0, Status 1, and Status 2
Message Switching - Technique used on some communications networks in which a message, with appropriate address information, is routed through one or more switching stations before being sent to its destination. On a typical message-switching network, a central computer receives messages, stores them (usually briefly), determines their destination addresses, and then delivers them to the appropriate party. Message switching enables a network to regulate traffic and to use communications lines efficiently.
Message Trailer - The service segment ending a message. [ISO 9735]
Message Type - An identified and structured set of data elements covering the requirements for a specified type of transaction, e.g. invoice. [ISO 9735]
Meta-data - Data about data. See Data Dictionary.
Metamodel - A model that defines the language for expressing a model.

Synonyms include "ontology," "schema," "semantic information model."
Metrics - A numeric measure of data that is used to evaluate entities or people.
Middleware - Software that provides a link between disparate applications, particularly software that links an application to a gateway or network. Most commonly used to link data bases. Middleware applications can exchange data directly with the back-end application system data base, theoretically eliminating the need to change the application to enable integration between the application system and the gateway. This is described as "eliminating" the need for Application Integration Software, but in actuality middleware is the application integration software.
Mirror Site - An internet site set up as a backup for a really busy site. It contains copies of all the files on the primary site. A mirror sites can spread the traffic load. Extremely busy sites may have several mirror sites.

Modems contain such built-in features as automatic phone dialing, auto answering, and redialing capabilities.
Multipurpose Internet Mail Extension (MIME) - An e-mail protocol that enables the transmission of non-ASCII messages over the internet. It is an extension of SMTP. MIME is what allows you to include different kinds of files as attachments, such as images, presentations, and formatted documents.
