| Name | Kind | Description |
| magnitude | attribute | Constraint on the magnitude of the DV_QUANTITY. |
| magnitude | attribute | |
| magnitude | operation | Numeric value of the date as days since the calendar origin point 1/1/0000. |
| magnitude | operation | numeric value of the date/time as seconds since the calendar origin point. |
| magnitude | operation | Effective magnitude represented by ratio. |
| magnitude | attribute | Numeric value of the quantity in canonical (i.e. single value) form. Implemented as constant, function or attribute in subtypes as appropriate. The type Ordered_numeric is mapped to the available appropriate type in each implementation technology. *** BEWARE *** |
| magnitude | attribute | |
| magnitude | operation | Numeric value of the time as seconds since the start of day. |
| magnitude_status | attribute | Optional status of magnitude with values: = : magnitude is a point value < : value is < magnitude > : value is > magnitude <= : value is <= magnitude >= : value is >= magnitude ~ : value is approximately magnitude If not present, meaning is = . |
| mandatory | attribute | Constant to indicate mandatory presence of something. |
| mappings | relation | Terms from other terminologies most closely matching this term, typically used where the originator (e.g. pathology lab) of information uses a local terminology but also supplies one or more equivalents from well known terminologies (e.g. LOINC). |
| match | attribute | The relative match of the target term with respect to the mapped text item. Result meanings: >': the mapping is to a broader term e.g. orginal text = arbovirus infection , target = viral infection =': the mapping is to a (supposedly) equivalent to the original item <': the mapping is to a narrower term. e.g. original text = diabetes , mapping = diabetes mellitus . ?': the kind of mapping is unknown. The first three values are taken from the ISO standards 2788 ( Guide to Establishment and development of monolingual thesauri ) and 5964 ( Guide to Establishment and development of multilingual thesauri ). |
| math_function | attribute | Mathematical function of the data of this event, e.g. maximum , mean etc. Coded using openEHR Terminology group event math function . |
| meaning | attribute | Used to describe the relationship, usually in clinical terms, such as in response to (the relationship between test results and an order), follow-up to and so on. Such relationships can represent any clinically meaningful connection between pieces of information. Values for meaning include those described in Annex C, ENV 13606 pt 2 under the categories of generic , documenting and reporting , organisational , clinical , circumstancial , and view management . |
| meaning | attribute | Term whose value indicates the meaning of this range, e.g. normal , critical , therapeutic etc. |
| measurement | package | The rm.support.measurement package defines a minimum of semantics relating to quantitative measurement, units, and conversion, enabling the Quantity package of the openEHR Data Types Information Model to be correctly expressed. As for the Terminology package, a simple service interface is assumed, which provides useful functions to other parts of the reference model. |
| measurement_class_diag (rm) | class diagram | |
| measurement_cv | class view | |
| measurement_dv | deployment view | |
| MEASUREMENT_SERVICE | class | Defines an object providing proxy access to a measurement information service. |
| MEASUREMENT_SERVICE | artifact | |
| media_type | attribute | Data media type coded from openEHR code set media types (interface for the IANA MIME types code set). |
| members | operation | List of constraints representing members of the container value of this attribute within the data. Semantics of the uniqueness and ordering of items in the container are given by the cardinality. |
| millisecond_validity | attribute | Validity of millisecond in constrained time. |
| millisecond_validity | attribute | Validity of millisecond in constrained time. |
| minute_validity | attribute | Validity of minute in constrained time. |
| minute_validity | attribute | Validity of minute in constrained time. |
| minutes_allowed | attribute | True if minutes are allowed in the constrained Duration. |
| misuse | attribute | Description of any misuses of the resource, i.e. contexts in which it should not be used. |
| mode | attribute | The mode of the performer / activity interaction, e.g. present, by telephone, by email etc. |
| month_validity | attribute | Validity of month in constrained date. |
| month_validity | attribute | Validity of month in constrained date. |
| months_allowed | attribute | True if months are allowed in the constrained Duration. |
| most_recent_version | operation | The version id of the most recent item, as a String. |
| most_recent_version_time_committed | operation | The commit date/time of the most recent item, as a String. |
