CV Presentation objects are the entry points for human users to the systems and services provided to access research data and their derived products.

In the ENVRI RM,  complex interactions between the components facilitating data use and other components are mediated by [[CV_Presentation_Objects#Virtual_laboratory|'''virtual laboratory''']]; these objects are deployed by [[CV_Presentation_Objects#Science_gateway|'''science gateways''']] in order to provide a persistent context for such interactions between groups of users and components within the RI.

The Reference Model recognises the following specific sub-classes of laboratory:

* [[CV_Presentation_Objects#Field_laboratory|'''field laboratory''']] (so-named because they interact with raw data sources 'in the field') are used to interact with the [[CV Data Acquisition|'''CV Data Acquisition''']] components, allowing researchers to deploy, calibrate and un-deploy instruments as part of the integrated data acquisition network used by an infrastructure to collect its primary 'raw' data. Field laboratories have the ability to instantiate new [[CV_Component_Objects#Instrument_controller|'''instrument controller''']] from the data acquisition set.
* [[CV_Presentation_Objects#Experiment_laboratory|'''experiment laboratory''']] are used to interact both with curated data and data processing facilities, allowing researchers to deploy datasets for processing and acquire results from computational experimentation.
* [[CV_Presentation_Objects#Semantic_laboratory|'''semantic laboratory''']] are used to interact with the semantic models used by a research infrastructure to interpret datasets and characteristic (meta)data.

Regardless of provenance, all laboratories must interact with a [[CV_Service_Objects#AAAI_service|'''AAAI service''']] in order to authorise requests and authenticate users of the laboratory before they can proceed with any privileged activities.

''Community portal for interacting with an infrastructure.''

A science gateway object encapsulates the functions required to interact with a research infrastructure from outside with the objects provided for data acquisition, data curation, data brokering and data processing. A science gateway should be able to provide virtual 'laboratories' for authorised agents to interact with and possibly configure many of the science functions of a research infrastructure. A science gateway is also known as a Virtual Research Environment.

* A science gateway object can instantiate any number of [[CV_Presentation_Objects#Virtual_laboratory|'''virtual laboratory''']] objects.

''Community proxy for interacting with RI components.''

A virtual laboratory object encapsulates interaction between a user or group of users and a subset of the science functions provided by a research infrastructure. Its role is to bind a [[CV_Service_Objects#AAAI_service|'''AAAI service''']] with (potentially) any number of other infrastructure objects.

A virtual laboratory object must provide at least one interface:

* '''authorise action (client)''' is used to retrieve authorisation for any restricted interactions with the data acquisition components.

Specific sub-classes of virtual laboratory should be defined to interact with the infrastructure in different ways. The ENVRI RM defines the [[CV_Presentation_Objects#Field_laboratory|'''field laboratory''']] object for interaction with the [[CV Data Acquisition|'''CV Data Acquisition''']] components.

''Community proxy for interacting with data acquisition instruments.''

A sub-class of [[CV_Presentation_Objects#Virtual_laboratory|'''virtual laboratory''']] object encapsulating the functions required to access, calibrate, deploy or withhold instruments during the data acquisition phase.

Deployment of an instrument entails the deployment of an instrument controller by which the instrument can be interacted with.

* A field laboratory object can instantiate any number of [[CV_Component_Objects#Instrument_controller|'''instrument controller''']] objects.

A field laboratory should provide at least two operational interfaces in addition to those provided by any virtual laboratory:

* '''calibrate instrument (client)''' is used to calibrate the reading of data by instruments based (in principle) on scientific analysis of data output. This interface can also be used to monitor activity on a given instrument.
* '''update registry (client)''' is used to register and/or withdraw instruments used for data acquisition.

'''Note'''<br>
A field laboratory is created by a science gateway in order to allow researchers in the field to interact with the data acquisition objects.

The degree of freedom with which a field laboratory interacts with other data acquisition objects is contingent on the nature of the research infrastructure and policed by a [[CV_Service_Objects#AAAI_service|'''AAAI service''']] object (as defined for all user laboratories).
