=== Defining the Database Identifier ===
 +
 +
A new database identifier is required for new data sources. Typically, source identifiers are extracted from the <tt>db</tt> attribute of <tt>primaryRef</tt> elements. These identifiers are then mapped to database identifiers in the iRefIndex <tt>int_db</tt> table.
 +
 +
For example, the InnateDB data file appears to employ the value <tt>innatedb</tt> to indicate that data originates from that particular source. Consequently, an <tt>int_db</tt> record must be defined, assigning a database identifier (an integer) which corresponds to this source identifier.
 +
 +
To define a new database identifier the <tt>Create_iRefIndex.sql</tt> file, which resides in the <tt>SQL</tt> directory of the <tt>BioPSI_Suplimenter</tt> software distribution, must be modified, adding a new statement as follows:
 +
 +
INSERT INTO int_db(id,name) VALUES(<database identifier>,'<source identifier>');
 +
 +
For example:
 +
 +
INSERT INTO int_db(id,name) VALUES(178,'innatedb');

See iRefIndex Issues and Notes for details of ongoing work to improve the iRefIndex software.

Adding Sources to iRefIndex

  1. Identify the location of the downloaded data.
  2. Evaluate the form of the data:
    1. For PSI MI XML (Molecular Interaction XML) documents, check the version of the format employed by the data documents.
    2. For the specific version, review the format's schema and how the data uses the schema. For example, PSI MI XML permits the specification of interactors within interaction descriptions as well as in a separate interactor list.
  3. Review existing, similar mapper definition files.

Evaluating the Data

The show_xml_paths.py script in the iRef_PSI_XML2RDBMS directory can be used to show the different element paths used in an XML data file to hold data items. For example:

python show_xml_paths.py --data /home/irefindex/data/MINT/2010-09-14/10023771.psi25.xml

The resulting list of paths indicates the places in the element hierarchy of a PSI-MI XML file where information is actually stored. For example:

entrySet/@level
entrySet/@minorVersion
entrySet/@version
entrySet/@xmlns
entrySet/@xmlns:xsi
entrySet/@xsi:schemaLocation

With this information, a suitable mapper file can be identified for the conversion of the XML-encoded data into tabular data to be stored in a database. In the above example, it is apparent that the experiment, interaction and interactor details reside alongside each other within each entry element:

entrySet/entry/experimentList/experimentDescription
entrySet/entry/interactionList/interaction
entrySet/entry/interactionList/interaction/participantList/participant
entrySet/entry/interactorList/interactor

In contrast, other PSI-MI XML files adopt a different structure which can be reduced to the following:

entrySet/entry/interactionList/interaction
entrySet/entry/interactionList/interaction/experimentList/experimentDescription
entrySet/entry/interactionList/interaction/participantList/participant

The different sources can be divided into a number of subformats as follows:

Subformat Sources Notes
Separate experiment, interaction, interactor lists BioGRID, HPRD, IntAct, MINT, OPHID BioGRID uses proteininteractor instead of interactor
OPHID uses proteinParticipant, proteinInteractor
Interaction contains experiment; separate interactor list DIP
Interaction contains experiment and interactor/participant BIND Translation, CORUM, InnateDB, MatrixDB, MPACT, MPPI InnateDB provides apparently redundant lists of experiments and interactors
MPPI uses proteinParticipant, proteinInteractor

Reviewing Mapper Files

The mapper files already in existence can be reviewed by using the show_xml_paths.py script together with one of these files which reside in the mapper subdirectory of the iRef_PSI_XML2RDBMS directory. For example:

python show_xml_paths.py --mapper mapper/Map25_CORUM.xml

The resulting output describes the structure of the data and how the mapper will attempt to interpret that data. For example (for CORUM):

Adapting an Existing Mapper File

Given an analysis of the data and the identification of the data's "subformat" (explained above), it should be possible to take an existing mapper file which supports the same subformat and to modify it to understand the new data source. For example, the InnateDB data resembles the data of various other sources (listed in the table above), and some comparisons of the structure of the data can be performed to see which source is closest in structure to InnateDB by using a diff-like program, potentially a graphical program such as kompare or kdiff3.

Once a similar source has been identified, the corresponding mapper file can be copied and modified. For example:

cp mapper/Map25_CORUM.xml mapper/Map25_InnateDB.xml

Then, it is necessary to update the new mapper file with details that differ from those in the closest source. In some cases, it can also be useful to consult other mapper files. For example, the following path may not be present in the CORUM mapper file despite being provided by the data file:

entry/experimentList/experimentDescription/hostOrganismList/hostOrganism

However, such information can be used by iRefIndex and may be supported by other mapper files. We may therefore decide to incorporate such information into our new mapper file (and perhaps into CORUM's mapper file, too). To do so, we first inspect other mapper files for the presence of such information and then isolate the section which supports its retrieval. For example, from the IntAct mapper file, using the show_xml_paths.py script...

python show_xml_paths.py --mapper mapper/Map25_INTACT_MINT_BIOGRID.xml --verbose

Here, the --verbose flag provides identifier information which makes finding the element, table and mapping definitions easier:

Element experimentDescription (grouper/id=3)...

  [...]

  Table int_name (sqlref/id=23)...
    _euid ...
      <incremental> (provides experimentDescription)
    _exorg ...
      entry/experimentList/experimentDescription/hostOrganismList/hostOrganism/@ncbiTaxId
    _exorgc ...
      38

From the above, it becomes apparent that we need a group definition for elementDescription, and that int_name must be populated according to the stated mappings for _euid, _exorg and _exorgc.

Fortunately, a group definition already exists in our new mapper file:

        <group  id ="3" element ="experimentDescription" parpos="4" atrib="_AUTO_">
            <path></path>
            <ref choice="no" />
        </group>

Meanwhile, the following table modifying section (corresponding to the identifier 23) must be located in the IntAct mapper file:

        <sql id="23" userefs="no" >
            <stmt>INSERT INTO int_name(uid,name,category) VALUES ('_euid','_exorg','_exorgc');</stmt>
            <variablelist>
                <variable name="_euid" ></variable>
                <variable name="_exorg"></variable>
                <variable name="_exorgc"></variable>
            </variablelist>
        </sql>

Since no conflicting section (with the same identifier for an sql element) exists in the new mapper file, this can be copied without changes. Then, it is necessary to ensure that mappings for _euid, _exorg and _exorgc are present; the following mappings happen to be found in the IntAct mapper file:

        <map id="42" sqlref="23"  name="_euid" grouper="3">
            <instruct>
                <param choice="yes" />
            </instruct>
        </map>
        <map id="43" sqlref="23"  name="_exorg" grouper="3">
            <instruct>
                <readfromfile choice="yes">
                    <path variable="_exorg" groupTag="ex" usetext="no" attribute="ncbiTaxId">entry,experimentList,experimentDescription,hostOrganismList,hostOrganism</path>
                </readfromfile>
            </instruct>
        </map>
        <map id="43" sqlref="23"  name="_exorgc" grouper="3">
            <instruct>
                <readfromfile choice="yes">
                    <path variable="_exorgc" groupTag="ex" usetext="no"  prefix="yes" val="38">entry,experimentList,experimentDescription,hostOrganismList,hostOrganism</path>
                </readfromfile>
            </instruct>
        </map>

Although _euid is a known name in the new mapper file already, no mapper definition exists to connect it to the table modification section (with identifier 23). Thus, it is necessary to copy the above mappings, to adjust their identifiers to avoid conflicts with other mappings, and to make sure that the grouper attributes refer to the correct group definition for experimentDescription. Fortunately, no such adjustments are required in this case and the definitions can be copied directly.

Choosing Sources of Data

In the above example, the hostOrganism information was extracted from the separate experimentList, but in order to maintain consistency with the other sources in the data file, we may choose a different source in the interactionList, particularly since the information appears to be duplicated in that location. Thus, a mapping is required that can extract data from the following path:

entry/interactionList/interaction/experimentList/experimentDescription/hostOrganismList/hostOrganism

Even if a mapping does not exist for the above path, there may be mappings involving similar paths:

entry/interactionList/interaction/experimentList/experimentDescription/interactionDetectionMethod/names/shortLabel

In this case, a different mapper file should be chosen to provide a suitable definition:

python show_xml_paths.py --mapper mapper/Map25_DIP.xml --verbose

A suitable section of that file can be summarised as follows:

Element experimentDescription (grouper/id=3)...

  [...]

  Table int_name (sqlref/id=15)...
    _euid ...
      <incremental> (provides experimentDescription)
    _idetlbl ...
      (intdetectionshortLabel) ...
      entry/interactionList/interaction/experimentList/experimentDescription/interactionDetectionMethod/names/shortLabel
      (intdetectionalias) ...
      entry/interactionList/interaction/experimentList/experimentDescription/interactionDetectionMethod/names/alias
      (intdtfull) ...
      entry/interactionList/interaction/experimentList/experimentDescription/interactionDetectionMethod/names/fullName
    _idetncat ...
      (intdetectionshlacategory) ...
      24
      (intdetectionoblac) ...
      25
      (indtcatful) ...
      26

The definitions involved can then be incorporated into the new mapper file, adjusting identifiers appropriately. Although the hostOrganism data in the above example originates from a different place in the element hierarchy, a simple path alteration to point to a location in the interactionList hierarchy is probably sufficient to make the initial mapping definitions consistent with the newly incorporated definitions for interactionDetectionMethod - the grouper identifiers for the mapping definitions refer to experimentDescription in all cases.

Defining the Database Identifier

A new database identifier is required for new data sources. Typically, source identifiers are extracted from the db attribute of primaryRef elements. These identifiers are then mapped to database identifiers in the iRefIndex int_db table.

For example, the InnateDB data file appears to employ the value innatedb to indicate that data originates from that particular source. Consequently, an int_db record must be defined, assigning a database identifier (an integer) which corresponds to this source identifier.

To define a new database identifier the Create_iRefIndex.sql file, which resides in the SQL directory of the BioPSI_Suplimenter software distribution, must be modified, adding a new statement as follows:

INSERT INTO int_db(id,name) VALUES(<database identifier>,'<source identifier>');

For example:

INSERT INTO int_db(id,name) VALUES(178,'innatedb');
