2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 aquifer system hydrogeological entity within which all components are in hydraulic continuity and that is bound by limits representing an obstacle for the dissemination of any perceptible effect outside the system 2.2 archive data data stored to keep knowledge about an object for a given period of time 2.3 attribute characteristic of an object or entity [ISO/IEC 11179-1] 2.4 calculated data data established from calculations carried out to reach different goals: forecast, simulation, design, etc. 2.5 concept unit of thought constituted through abstraction on the basis of characteristics common to a set of objects
2.6 data representation of facts, concepts, or instructions in a formalized manner, suitable for communication, interpretation, or processing by humans or by automatic means
2.7 data element unit of data for which the definition, identification, representation, and
permissible values are specified by means of a set of attributes [ISO/IEC 11179-1]

2.9 data interchange process of sending and receiving data in such a manner that the information content or meaning assigned to the data is not altered during the transmission 2.10 data length maximum size given in a number of characters
2.11 data producer private or public entity in charge of data production and responsible for the validity of these data when they are published
2.12 data model description of the organization of data in a manner that reflects an information structure
NOTE See Annex A. 2.13 data type format used for the collection of letters, digits, and/or symbols, to depict values of a data element, determined by the operations that may be performed on the data element
2.14 definition statement that expresses the essential nature of a data element and permits its differentiation from all other data elements 2.15 entity any concrete or abstract thing of interest, including associations among things 2.16 information (in information processing): knowledge concerning objects, such as facts, events, things, processes, or ideas, including concepts, that within a certain context has a particular meaning 2.17 metadata data that defines and describes other data [ISO/IEC 11179-1] 2.18 object any part of the conceivable or perceivable world
2.19 real time data data generally taken from devices for the immediate knowledge of a phenomenon state

Figure 4 — Continuous time series presentation 4.1.4 Validation of the measurements The validity of each measurement is described according to the type of measurement method used. Four scenarios are possible: a) Impossible to validate;

Suspect ;
d) Not valid ; By default, all values are specified as ‘Not validated yet’. The operator shall then assign one of the above- mentioned qualifications after examination. A measurement is validated when the producer believes that the data and all the different procedures used to produce them comply with the monitoring protocol. A measurement is not valid when the producer believes that the data or the procedures used to produce them do not comply with the measurement protocol. A measurement is "Impossible to validate" when the operator does not have the information available to determine the validity of the data production according to the measurement protocol ( e.g. historical data from archives). 4.2 Piezometer station 4.2.1 General A piezometer is one method of measuring the piezometric height at a point within an aquifer system. It indicates the pressure at this point, enabling the observer to record the phreatic level or pressure. In the data interchange, only the depths to groundwater level of a piezometer are exchanged.
According to the scope of this standard, the concept of "piezometer" is extended to all artificial structures (well, borehole, gravel-pit) or natural structures (swallow, hole, grottos) which enables the groundwater level to be measured. Each piezometer shall have a unique code given by the country where it is located. 4.2.2 Key features of a piezometer 4.2.2.1 General Each piezometer has two key features: the level measurement point and the altitude benchmark measurement point as shown in Figure 5.
