Create Code System

Create a new Code System to contain a
set of new coded concepts. The Code System
is created by defining the set of meta-data
properties that describe it.

LexEVS provides ability to load Code System
from various source format.
Here are the loaders available:

• HL7 RIM DB
• LexGrid Text file
• LexGrid XML file
• NCI MetaThesaurus
• OBO
• OWL
• RedLex Protégé Frames
• UMLS Semantic Net
• UMLS Source From RRF files
• UMLS Source From SQL

Maintain Code System Version

Update Code System meta-data properties.

The LexEVS Authoring services will provide
ability to update meta-data of a
Code System as well as all its entities.

Update Code System Version Status

Changes the status of a code system version
(suspended, reinstated, canceled, removed).

The LexEVS Authoring services will provide
ability to modify the status of a Code System version.

Create Code System Supplement

Create a new Code System Supplement as a
container of a set of concepts and concept properties
to be appended to a target code system.
Does not add the concepts and properties.

LexEVS treats Code System Supplement as any
other Code System. The URI of target Code System will be
included in SupportedCodingScheme and imported flag will be set
to 'true'. All the contents of target/base Code System will
be imported into this Supplement Code System.
The rest of the function will be similar to 'Create Code System'
described above

Maintain Code System Supplement

Update Code System Supplement meta-data properties
and add concepts and properties to code system.

The LexEVS, Code System Supplement is treated
like any other Code System, thus provides an
ability to update its meta-data properties,
add or modify concepts and its properties.

Create Concept

Create concept to be included in a Code System.
The new concept is defined by the set of
meta-data properties that describe it,
which may include its proper placement via association
binding within the hierarchy of the Code System.

The LexEVS Authoring services will provide
ability to add and update entities in a Code System.

Maintain Concept

Update Concept meta-data properties.

The LexEVS Authoring services will provide
ability to add and update entities in a Code System.

Update Concept Status

Changes the status of a code system concept
(suspend, reinstate, cancel, remove).

The LexEVS Authoring services will provide
ability to add and update entities in a Code System.

Create Association Type

Create a new relationship type
(as intended by the association type class of the conceptual model),
an instance of which may be used to link two concepts.
A list of code system IDs can be supplied if the intent
is to restrict use to specific code systems. The default is
availability to all code systems present on the server.

The LexEVS Authoring services will provide
ability to create and maintain entities of type
Association in a Code System.

Maintain Association Type

Update or deprecate an Association type that may
be used to link two concepts.

The LexEVS Authoring services will provide
ability to create and maintain entities of type
Association in a Code System.

Create Value Set

Create a Value Set (extensional or intensional)
that is defined by a computable expression
that can be resolved to an exact list of
coded concepts at any given point in time.

The LexEVS Authoring services will provide
ability to create and maintain value set definitions.

Maintain Value Set

Update properties or expression of a value set definition
(extensional and intensional value sets).

The LexEVS Authoring services will provide
ability to create and maintain value set definitions.

Update Value Set Status

Changes the status of a value set version
(suspend, reinstate, cancel, remove).

The LexEVS Authoring services will provide
ability to create and maintain value set definitions.

Create Concept Domain

Create a Concept Domain.

In LexEVS, a coding scheme can contain entities
of type 'Concept Domain'. So similar to
function 'Create Concept', an entity of type
'concept domain' can be added and maintained
in a coding scheme. And similar to an entity
of type 'concept', concept domain can have
properties, participate in associations etc.

Maintain Concept Domain

Update properties of a Concept Domain, including
bindings to value sets within usage contexts

Similar to 'maintain concept' function described
above, in LexEVS, a coding scheme can contain
entities of type 'Concept Domain' and it can
be added or modified (including its properties)
in a coding scheme. Any changes to the value set
binding should be performed separately using
'maintain value set' function.

Create Usage Context

Create a Usage Context.

Similar to 'create concept domain' function
described above, in LexEVS, a coding scheme
can contain entities of type 'Usage Context'
and it can be added or modified in a coding scheme.

Maintain Usage Context

Update properties of a Usage Context

Similar to 'maintain concept' function
described above, in LexEVS, a coding scheme
can contain entities of type 'Usage Context'
and it can be added or modified
(include its properties) in a coding scheme.

Update Association Status

Update the status of an association
(active, inactive, cancelled etc). This allows
a Terminology User to activate or inactivate
a given association, thus changing its availability
for access by other terminology service functions

LexEVS Authoring API provides
ability to change the status of an association
(a triple).

Create Association

Relates a single specific coded concept
within a specified code system (source) to a
corresponding single specific coded concept
(target) within the same or another code
system, including identification of a
specified Association type.

LexEVS Authoring API provides ability
to create and maintain association
between coded concepts from one
or more code system.

*Create Lexical Association
between Coded Concept*

Relates a set of one or more coded concepts
within a specified code system
(source)to a corresponding set of
one or more coded concepts (target)
within that system or another code
system using a set of lexical rules
(matching algorithms) to generate
the Association. The
"Source Search Criteria" allows
for identification of a subset
of the Source Code System to apply
the matching algorithm to, if
required (this may include
limiting the version of the
code system).

This functionality is out of scope for this release.

*Create Rule Based Association
between Coded Concept*

Relates a set of zero or more coded concepts
within a specified code system
(source)to a corresponding set of
zero or more coded concepts (target)
within that system or another code
system using a set of description
logic or inference rules that either
assert or infer Associations.
The "Source Search Criteria"
allows for identification of a
subset of the Source Code System
to apply the matching algorithm too,
if required (this may include
limiting the version of the code
system).

This functionality is out of scope for this release.
