Solutions Architecture: XML Loads of LexGrid Modeled Content h4. *Overview:* *Loads of LexGrid XML were formerly limited by the size of the Coding Scheme model element that could be constructed in memory. &nbsp;* \\ *Loaded models had a single entry point at the CodingScheme element.&nbsp; With the intention of providing improved loading performance,* \\ *access points to other levels of LexGrid Model elements, and a convenient format for authoring, the design of the 5.1 XML Loader has been* \\ *updated for LexEVS 6.0 and will be implemented with the following considerations: &nbsp;&nbsp;* * *&nbsp;A streaming implementation of the loading mechanism allowing larger loads in a smaller memory footprint.* * *A variety of entry points to facilitate loading of Revisions, System Releases, Value Sets, Pick Lists, and Coding Schemes.* * *A loading mechanism for Authoring based manipulation of LexGrid based xml files allowing entities and associations to be added* \\ *to a given coding scheme in XML, then loaded into a LexGrid data repository.* h5. Streaming XML Implementation \\ *The latest implementation of the LexGrid XML loader provides a partitioned load of a coding scheme or other potentially large elements.* *The 6.0 loader will read coding scheme meta data into memory, load it to the LexGrid database and then begin stepping through entities and associations&nbsp;* *persisting elements to the database and then removing them from the coding scheme object as the unmarshaller reads objects from XML and into the coding scheme* *object in memory.&nbsp; Streaming XML reads while controlling the build of the coding scheme (and potentially other objects) in memory allowing the load of* *far larger terminologies constructed in LexGrid xml.&nbsp; This also allows users to eventually export larger coding schemes, revise them with authoring tools,* *and reload them as LexGrid Revision elements. &nbsp; This and other authoring scenarios will be exercised upon LexGrid XML with subsequent loads to the* *LexGrid database possible.&nbsp; (See authoring design below.)* \\ *LexGrid coding scheme meta data contains an number of required and optional elements as defined in the LexGrid schema.&nbsp; The last of these elements, before entity and associations* *are expressed, are the coding scheme mappings and the coding scheme properties.&nbsp; Mappings are required elements in the coding scheme and as* *such are a default stopping point of coding scheme reads. Coding scheme properties are not required and as such may not exist in a given rendering of LexGrid XML.* *Before persistence of meta data to the LexGrid database takes place, a high speed pass is made over the coding scheme meta data portion of the XML with the STAX* *parser api to determine coding scheme properties presence. &nbsp;* \\ \\ !XMLMetaDataReads.png!\\ \\ *The bulk of the coding scheme elements are read, stored to database, and de-referenced to allow sufficient memory management.* \\ \\ !EntityReadandDeref.png!\\ \\ !assocReadandDeref.png!\\ h4. Entry Points Expanded h5. Coding Scheme Entry Point *Previously, coding scheme was the only entry point for persisting loading to the LexGrid data base.&nbsp; Since pick lists, value domains, and revisions* *required more flexibility in XML based loads,&nbsp; entry points for revisions and system releases were also added.* \\ !CodingSchemeEP.png!\\ h5. &nbsp;Revision Entry Point \\ *Revisions can be applied to Coding Schemes, Pick Lists and Value Sets.&nbsp; A single revision element can load a set of revisions of coding schemes, pick lists and value sets.* \\ !RevisionEP.png|width=898,height=880! \\ *Revision can contain a variety of changed elements.* \\ \\ !RevisionEPAll.png! h5. &nbsp;System Release Entry Point \\ *System Release is primarily intended as a release point for collections of pick lists and value sets.&nbsp; It is beyond* *the scope of this implementation to load multiple coding schemes contained within a system release.&nbsp; The technical* *problems implied by the loads of a System Release containing multiple large coding schemes suggests that such a use case* *is impractical in many scenarios.* \\ \\ !SystemReleaseEP.png! &nbsp; h3. Solutions Architecture: Associations and Mapping Placeholder for mapping designs \\ !Arch_sol_Association_mapping.png|width=799,height=767!\\ h5. &nbsp;Levels of Mapping Implementation implied by current requirements from various stakeholders There are multiple levels at which mapping, as evaluated here, could be considered to be "supported": # The ability to store map sets, look up map sets by id, from, to \\ and other attributes and to look up entries by source, target and/or \\ relationship. We would have to store all of the additional information \\ such as options, rules, categories, advice, etc, but it would be up to \\ external software to interpret and evaluate the contents. \\ # Everything in option 1) above plus the ability to query \\ additional fields - give me an ordered, structured list of a mapping \\ entry in a way that someone could write a standard interpreter to \\ evaluate it - this would basically require the addition of a model and \\ would most likely cause us to split from the existing relations model, \\ as it gets into the domain of table driven rule sets. # Everything in 1) and, possibly 2) with the added ability to \\ actually interpret the rules - an API that answers questions such as \\ "What information is needed to map 231754000 (poisoning by sodium \\ valproate) correctly?" (answer - whether barbituates, sulfonamides were \\ present, whether combined with various substances, etc). "What does \\ 231754000 in the presence of ... map to? h5. h5. Evaluation of Levels of Mapping Implementation for CTS 2 For LexEVS 6.0 (CTS 2), (3) is out of scope. This is \\ the function of a rules engine and the complexities of even the supplied \\ examples are overwhelming. We may want to examine the DSS RFP to see \\ whether there is anything there that applies. It appears that (2) \\ is out of scope as well, as, whether we interpret the semantics of the \\ rules or not, the structure required to represent the rules still lies \\ well within the rule base and DSS space. The question is, then, whether \\ item (1) adds sufficient value to be worth doing. My take is "no" as \\ well, as trying to fit all of the various aspects of the mapping rules \\ that we've seen to date into the nooks and crannies of the LexGrid \\ mapping model seems to be an exercise with little return. What we need to do is to return to the set of use cases, if any, \\ that LexEVS could reasonably resolve. As there _are_ simpler use \\ cases, such as those presented by various stakeholders, we will clearly need to \\ resolve them and, if it would be useful, could answer the same questions \\ for complex mappings. Once, however, we get to the point of \\ determining what participates in a particular map, it seems like we are \\ getting out of our scope - the best we might do is supply the \\ associationId that could be used as an index into another table. h5. Proposed Solution \\ {color:#0066cc}{*}Model Changes{*}{color} !Model_changes_mapping_1.PNG|width=987,height=588!\\ The relations attribute in the model will have the following elements and attributes added: * representsVersion - if present, the source asserted version of the collection of relations or mappings * isMapping - if true, this collection of relations represents a mapping and will be evaluated for "mapping" related queries. * sourceCodingScheme - if present, the local identifier of the namespace that the sourcEntityCodes are derived from. * &nbsp;sourceCodingSchemeVersion - the source asserted version identifier of the source coding scheme.&nbsp; If present, this becomes the default for sourceEntityCodeNamespace. * targetCodingScheme - if present, the local identifier of the namespace that the targetEntityCodes are derived from. If present, this becomes the default for targetEntityCodeNamespace. * targetCodingSchemeVersion - the source asserted version identifier of the target coding scheme * properties - all other properties on the "relations bucket" level that don't fit one of the items in the Relations container !Model_changes_mapping_2.PNG! &nbsp; There are no additional changes for the second part of the model, shown above. h2.

Expression Issues One of the requirements for mapping has been the ability to discover what maps a given entity (may) participate in. \\ This will not be completely answerable in situations where the codes are carried in text expressions. One alternative \\ would be to parse the target expression when possible and to create multiple rows, one for each target. Besides the parsing \\ complexity, however, the other issue is that it is not possible to record the expression operators (AND, OR, ...) \\ in the expansion. This, however, would arguably be the best use of the mappings for this level of complexity. \\ h5. &nbsp;Sample Mapping XML \\ \\ {code:xml} <?xml version="1.0" encoding="UTF-8" ?> - <codingScheme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://LexGrid.org/schema/2010/01/LexGrid/codingSchemes file:/C:/devel/v6/lexgrid_model/lgModel/master/relations.xsd" xmlns="http://LexGrid.org/schema/2010/01/LexGrid/codingSchemes" xmlns:lgBuiltin="http://LexGrid.org/schema/2010/01/LexGrid/builtins" xmlns:lgCS="http://LexGrid.org/schema/2010/01/LexGrid/codingSchemes" xmlns:lgCon="http://LexGrid.org/schema/2010/01/LexGrid/concepts" xmlns:lgCommon="http://LexGrid.org/schema/2010/01/LexGrid/commonTypes" codingSchemeName="UMLS" codingSchemeURI="urn:oid:2.16.840.1.113883.6.2" representsVersion="http://SharedNames.org/ontology/umls/2009AB"> <mappings /> - <!-- MRSAT entry C1306694|L8923988|S11111536|A17029750|CODE|1000|AT115321814||MAPSETVERSION|MTH|2010_2009_08_17|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT115321815||TOVSAB|MTH|MSH2010_2009_08_17|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT37361323||FROMRSAB|MTH|MTH|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT37361327||FROMVSAB|MTH|MTH|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT37361343||MAPSETGRAMMAR|MTH|ATX ::= expr; expr ::= disj; disj ::= conj , conj "OR" conj; conj ::= unary , unary "AND" unary; unary ::= neg , pos; neg ::= "NOT" pos; pos ::= "(" expr ")" , slash , atom; slash ::= atom , atom "/" atom; atom ::= "<" (any non ">" character) ">";|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT37361355||MAPSETRSAB|MTH|MTH|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT37361364||MAPSETTYPE|MTH|ATX|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT37361368||MAPSETVSAB|MTH|MTH|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT37408395||TORSAB|MTH|MSH|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT37424062||SOS|MTH|This map set contains mappings from Metathesaurus CUIs to MSH associated expressions.|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT56870375||MTH_MAPFROMEXHAUSTIVE|MTH|N|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT56870378||MTH_MAPSETCOMPLEXITY|MTH|ONE_TO_ONE|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT56870384||MTH_MAPTOEXHAUSTIVE|MTH|N|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT65576316||MTH_MAPFROMCOMPLEXITY|MTH|SINGLE CUI|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT65576317||MTH_MAPTOCOMPLEXITY|MTH|BOOLEAN_EXPRESSION STR|N|| C1306694|L8923988|S11111536|A17029750|CODE|1000|AT67813929||MAPSETSID|MTH|1000|N|| C1306694||||CUI||AT116199817||MR|MTH|20090921|N|| C1306694||||CUI||AT31823722||DA|MTH|20040415|N|| C1306694||||CUI||AT31952620||ST|MTH|R|N|| --> - <!-- OPTION 1: Everything flattened --> - <lgCS:relations containerName="C1306694" isMapping="true" sourceCodingScheme="MTH" sourceCodingSchemeVersion="MTH" targetCodingScheme="MSH" targetCodingSchemeVersion="MSH2010_2009_08_17" representsVersion="2010_2009_08_17" xmlns="http://LexGrid.org/schema/2010/01/LexGrid/relations"> - <!-- This should be MAPSETNAME but, curiously, it is missing from the MRSAT list.

Solution Architecture h5. Data Access Layer LexEVS lacks a generalized Read/Write interface that can support Authoring and incremental Coding Scheme changes. Also, database access is not isolated. Database-specific code is intermixed with the Service Layer, as well as Extensions. To make LexEVS more able to handle Authoring, while at the same time providing a clean, centralized Database Access Layer, these are the requirements: * Service Layer code should not call any JDBC code other than a Data Access Interface * The Data Access Layer should allow connection pooling * The Data Access Layer should expose 'Service' or 'Repository' Interfaces to the Service Layer. * Transactions should be well defined * Allow for Backwards Compatibility * Inserts, Updates, Selects, and Deletes should cascade the Object hierarchy if desired * Service-Exposed Interfaces should use the Castor-generated beans. * Batch inserts should be supported * Lucene access should be included in the Data Access Layer * Registry accesss should be included in the Data Access Layer. * Expose an Event-Driven framework to allow users to insert business rules to control access to the database * In terms of System Resource responsibilities, the Data Access Layer should be responsible for: ** Detecting the LexGrid Schema version ** Detecting the Database Type (MySQL, Oracle... etc) ** Producing appropriate implementations of the Database Access code given the above ** Loading and initializing all schemas on install ** Tracking loaded Coding Schemes and other resources ** All database admin functions (remove Coding Scheme, index, compute transitivity, etc) h2.

Structure of the CTS 2 Service


The functional CTS 2 Model defines several functional profiles.  These profiles are a focused subset of the functionality of a CTS 2 implementation.

 CTS 2 Query Profile:

  • Searching and querying terminologies
  • Provide access to terminology content and representational structures (description logic) consistent with the terminology author's intent.

 Terminology Administration Profile:

  •  Restricting administrative access
  •  Obtaining and loading terminologies
  •  Maintaining terminology access
  • Control Content Access

 Terminology Authoring Profile:

  • functional terminology analysis/query
  • direct terminology edits

Semantic Profiles

 HL7 Profile:

  • Functional coverage and specificity necessary for HL7 conformance
  • Searching terminology content
  • Interchange content in the the Model Interchange Format.
  • Use of HL7 Datatypes
  • (Model Interchange Format (MIF) Representation of terminology content

Mature Terminology Profile:

  • Best practices conformance for the terminology

Developing Terminology Profile:

  • ad hoc or degraded terminologies

Solution Architecture

Data Access Layer

LexEVS lacks a generalized Read/Write interface that can support Authoring and incremental Coding Scheme changes. Also, database access is not isolated. Database-specific code is intermixed with the Service Layer, as well as Extensions. To make LexEVS more able to handle Authoring, while at the same time providing a clean, centralized Database Access Layer, these are the requirements:

  • Service Layer code should not call any JDBC code other than a Data Access Interface
  • The Data Access Layer should allow connection pooling
  • The Data Access Layer should expose 'Service' or 'Repository' Interfaces to the Service Layer.
  • Transactions should be well defined
  • Allow for Backwards Compatibility
  • Inserts, Updates, Selects, and Deletes should cascade the Object hierarchy if desired
  • Service-Exposed Interfaces should use the Castor-generated beans.
  • Batch inserts should be supported
  • Lucene access should be included in the Data Access Layer
  • Registry accesss should be included in the Data Access Layer.
  • Expose an Event-Driven framework to allow users to insert business rules to control access to the database
  • In terms of System Resource responsibilities, the Data Access Layer should be responsible for:
    • Detecting the LexGrid Schema version
    • Detecting the Database Type (MySQL, Oracle... etc)
    • Producing appropriate implementations of the Database Access code given the above
    • Loading and initializing all schemas on install
    • Tracking loaded Coding Schemes and other resources
    • All database admin functions (remove Coding Scheme, index, compute transitivity, etc)
