POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
The description of the composition of a specific fluid phase expressed in terms of the fluid components found within the phase.
- fluid_phase (M, K: specific_fluid_phase(fluid_phase_composition))
- This defines the fluid phase being described by this composition. Each fluid_phase_composition must be a part of one specific_fluid_phase.
- fluid_system_state (O, K: fluid_system_state(fluid_phase_composition))
- Specifies the environmental conditions associated with the relationship between a fluid phase and its material components. Each fluid_phase_composition may be defined at one fluid_system_state.
- fluid_component (M, K: fluid_component(fluid_phase_composition))
- This is the fluid component that is being described as a component of the fluid phase. Each fluid_phase_composition must describe the occurrence of one fluid_component.
- description (O, I: ndt_comment) (C117)
- A remark or comment about the instance. Inherited from e_and_p_data.
- instance_create_date (O, I: ndt_date_tod) (C126)
- This is the date that this instance was created. This date is defined by the source if imported, or is the date the instance is created if a new instance. Inherited from e_and_p_data.
- instance_creator (O, I: ndt_identifier) (C126)
- This is the person, company or application that created this instance. This identifies the party responsible for loading this instance. Inherited from e_and_p_data.
- last_updated (O, I: ndt_date_tod) (C126)
- This is the date that this instance was last updated. This value should be updated when any part of this instance is altered (except for inverse relationships). Inherited from e_and_p_data.
- last_updated_by (O, I: ndt_identifier) (C126)
- This records the person or application making the update to this instance. Inherited from e_and_p_data.
- source (O, I: ndt_identifier) (C126)
- The provider of this instance, which is usually a data provider for imported/purchased data. If this instance is provided by POSC, then this attribute must be "POSC". Inherited from e_and_p_data.
- data_collection (I, V: SET[0:?] data_collection_content(collection_part)) (C020)
- Indicates the data collections that include this instance of E and P data. Each fluid_phase_composition may be a member of one or more data_collection_content. Inherited from e_and_p_data.
- document_information_content (I, V: SET[0:?] document_information_content(e_and_p_data)) (C136)
- These are the document specification parts that include this data value and define its meaning within a document specification. Each use may define a different meaning, and many uses are allowed. Each fluid_phase_composition may be included in one or more document_information_content. Inherited from e_and_p_data.
- graphical_element (I, V: SET[0:?] graphical_element(depicted_object))
- Specifies one or more graphical elements which are depicting this data item. Each fluid_phase_composition may be depicted by one or more graphical_element. Inherited from e_and_p_data.
- pty_absolute_abundance (V: SET[0:?] pty_absolute_abundance(fluid_phase_composition))
- Each fluid_phase_composition may have a property of one or more pty_absolute_abundance.
- pty_fl_phase_component_dist (V: SET[0:?] pty_fl_phase_component_dist(fluid_phase_composition)) (C112)
- Each fluid_phase_composition may have a property of one or more pty_fl_phase_component_dist.
- pty_mass_fraction (V: SET[0:?] pty_mass_fraction(fluid_phase_composition))
- Each fluid_phase_composition may have a property of one or more pty_mass_fraction.
- pty_mole_fraction (V: SET[0:?] pty_mole_fraction(fluid_phase_composition))
- Each fluid_phase_composition may have a property of one or more pty_mole_fraction.
- pty_volume_fraction (V: SET[0:?] pty_volume_fraction(fluid_phase_composition))
- Each fluid_phase_composition may have a property of one or more pty_volume_fraction.
Local rules:
- Uniqueness Constraint
- fluid_phase, fluid_system_state, fluid_component
- Same Related Instance
-
Each FLUID PHASE COMPOSITION defined at an instance of FLUID SYSTEM STATE must be a part of an instance of FLUID PHASE that is defined for the same instance of FLUID SYSTEM STATE.
