Introduction:

This document describes an the MAGE-TAB model, designed to contain the contents of files parsed in MAGE-TAB v1.0 and v1.1 format. The motivation is primarily to integrate MAGE-TAB format data sets from existing resources into one simple system. The aim is to produce an open source MAGE-TAB database and import/export tools to read and write MAGE-TAB formatted data. MOLGENIS is being used to autogenerate such database by describing the data model in its markup language and has useful features including rapid model development, user interfaces, and R and java APIs. Import/export tools can then be easily created against these APIs (in progress).

This data model support MAGE-TAB 1.1 IDF, SDRF, ADF and data file formats and is an extension of previous MAGE-TAB models (Maier et al 2006.) The model documentation includes a description of each data types, explanations of design decisions and examples of MAGE-TAB documents in the ArrayExpress repository. The MAGE-TAB model has been mapped to FuGE and equivalent FuGE classes are provided in the object documentation. This documentation was autogenerated from MOLGENIS model files. Find the complete sources at: magetab_idf.xml , magetab_adf.xml , magetab_sdrf.xml and magetab_data.xml .

Identifiable (interface).

For modeling and implementation purposes, all objects in MAGE-TAB model that have an id and name inherit from identifiable. Other classes in the model can be specified as sub-classes, inheriting from Identifiable. Identifiable gives classes a unique identifier within the scope and a name that need not be unique. Also it is possible to add comments to any objects; in the MAGE-TAB format this is implied if a Comment[name] is added after/next to the elements that needs to be commented
Simplification of FuGE::Identifiable/FuGE::Describable, generalizing all describables to NVT.

NameValueType

NameValueType is used generically to represent comments from all parts of the MAGE-TAB specification in this model. All objects that are instantiated can have NVT associated, so abstract classes are excluded. See MAGE-TAB specification for detailed examples.

OntologyTerm

A single entry from an ontology or a controlled vocabulary. If it is a simple controlled vocabulary, there may be no formal accession for the term. In these cases the local name should be repeated in both term and termAccession. If the term has a value, the OntologyIndividual will have a single DataProperty whose value was the value for the property. For instance, for an OntologyIndividual based on the MO ontology the attributes might be: The term would be what is usually called the local name in the Ontology, for instance 'Age'; The termAccession could be 'http://mged.sourceforge.net/ontologies/MGEDOntology.owl#Age' or a an arbitrary accession if one exists; The identifier is a unique identifier for individuals in the scope of the FuGE instance; The inherited name attribute should not be used; The ontologyURI of OntologySource could be 'http://mged.sourceforge.net/ontologies/MGEDOntology.owl". The OntologyTerm subclasses are instances of Ontology classes and properties, not the actual terms themselves. An OntologyIndividual, if based on an existing Ontology, can be considered a statement that can be validated against the referenced ontology. The subclasses and their associations are based on the Ontology Definition Model, ad/2005-04-13, submitted to the OMG as a response to RFP ad/2003-03-40, Copyright © 2005 DSTC Pty Ltd.

Investigation

Investigation is a high level object that represents information about a biological investigation. Ontology Terms are used to describe design type, quality control, replicate design. A title and description provide free text descriptions of the Investigation. Note that Investigation can be using one or more technologies such as Genotyping and Gene Expression. Version is an additional attribute of the 1.1 MAGE-TAB version and is included to represent the format version NOT the version of the Investigation. Investigation and Experiment are considered synonyms in this model, both are used interchangeably in the MAGE-TAB specification. A URI has been included in the model to refer to SDRF and ADF files that do exist locally. Example E-MTAB-506 ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/TABM/E-TABM-506/E-TABM-506.idf.txt .
The FuGE equivalent to Investigation is FuGE::Investigation.

Factor

Factor represents the investigators INTENDED variable within an Investigation. Example being in cancer studies, whether the subject has cancer or not is an intended variable, whereas the age difference between the subjects (although definitely variable) may be unimportant in the particular study design and shouldn't be reported as Factor. Typically this correlates with the design type of investigation. For example a design in which a disease versus normal is investigated is a disease state design and the corresponding Factor would be of type disease state. Factors have an association to FactorValue where the values are instantiated as ontology terms or measurements. An example of factor can be seen in E-MTAB-506 ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/TABM/E-TABM-506/E-TABM-506.idf.txt .

Person

Person represents one or more people involved with an Investigation. This may include authors on a paper, lab personnel or PIs. Person has last name, firstname, mid initial, address, contact and email. A Person role is included to represent how a Person is involved with an investigation. For submission to repository purposes an allowed value is 'submitter' and the term is present in the MGED Ontology, an alternative use could represent job title. An Example from ArrayExpress is E-MTAB-506 ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/TABM/E-TABM-506/E-TABM-506.idf.txt. .

Publication

Publication is part of the Investigation package and is used to represent information about one or more publications related to an Investigation. The publication need not only be primary publication for an Investigation but may also represent other related information- though this use is less common. Publications have attributes of publications Authors and also DOI and Pubmed identifiers (when these are available). These are represented as OntologyTerms as in the MAGE-TAB model all 'xrefs' (cross references) for ontologies and accession numbers are handled generically. An example of a publication is available in an IDF file from ArrayExpress is experiment E-MTAB-506 ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/TABM/E-TABM-506/E-TABM-506.idf.txt.

Protocol

Protocol is a high level object that represents the details of protocols used during the investigation. The uses of Protocols to process BioMaterials and Data are referenced by ProtocolApplication (in the SDRF part of the format). Protocol has an association to OntologyTerm to represent the type of protocol. Protocols are associated with Hardware, Software and Parameters used in the Protocol. An example from ArrayExpress is E-MTAB-506 ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/TABM/E-TABM-506/E-TABM-506.idf.txt.

adf package

This package models Array Design Format (ADF) - defining each array type used. An ADF file describes the design of an array, e.g., what sequence is located at each position on an array and what the annotation of this sequence is. If the investigation uses arrays for which a description has been previously provided, such as a standard commercial array, cross-references to entries in a public repository (e.g., an ArrayExpress accession number) can be included instead of explicit array descriptions.

DesignElement (interface).

Artificial class for modeling purposes. Acts as the generalization of any property of an ArrayDesign such as Reporter and Feature. The Nearest FuGE equivalent is DimensionElement but an Array specific extension was needed.
There is no direct equivalent of DesignElement in FuGE.

ArrayDesign

The ArrayDesign is used to represent the information about e.g. a microarray. The attributes are required to fulfill the MIAME conditions regarding surface type, polymer type etc and an association to ProtocolApplication is used to describe the details of Array production typically for self made rather than commercial arrays. The ArrayDesign is a high level object. ArrayDesign has associations to Features, Reporters and CompositeElements (previously called CompositeSequences in MAGE-OM 1.0) which describe layout of the ArrayDesign. ArrayDesign is only required for Array based experiments which use a traditional type microarray where layout and relationships of probes are important to detect layout effects.
There is no direct equivalent of ArrayDesign in FuGE, Protocol and/or Equipment is likely the nearest map as an Array specific extension was needed.

Feature

Feature represents the location of some material deposited at a specific place on an array. Feature has coordinates - BlockColumn, BlockRow, Column, Row. This concept is described in ArrayExpress documentation http://www.ebi.ac.uk/miamexpress/help /adf/ and an example of a correctly formatted ADF can be seen in the MAGE-TAB specification v1.0 document.

sdrf package

This package models MAGE-TAB Sample and Data Relationship Format (SDRF) - a tab-delimited file (or files) describing the relationships between samples, arrays, data, and other objects used or produced in the investigation, and providing all MIAME information that is not provided elsewhere. This is often the least trivial part of the experiment description due to the typically large graph of complex relationships which are possible between samples and their respective hybridizations; however, for simple experimental designs, constructing the SDRF file is straightforward, and even complex loop designs can be expressed in this format.
To make this graph explicit, all relationships ar modelled as Nodes and Edges, with the Nodes being tangible elements of the experiment like Material or Data files, and the Edges to represent the treatments that produced them. These edges can be annotated with zero-or-more Protocol Applications. This grouping of Protocol Applications is expected to make experiment modeling more flexible than FuGE.

Edge

An Edge is a generic object that is used to describe the treatments between Materials and Data in an experiment (i.e. the Nodes of the experiment graph). An Edge can be annotated with ProtocolApplications using the reference from ProtocolApplication to Edge. It has no explicit equivalent in the MAGE-TAB format specification but acts as a container for chain of zero-or-more ProtocolApplications that can be added, e.g. between Source, Sample, Assay, etc. See example, E-MTAB-506 ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/TABM/E-TABM-506/E-TABM-506.idf.txt
There is no FuGE equivalent to Edge, closest match is FuGE::ProtocolApplication.

ProtocolApplication

ProtocolApplications are used in MAGE-TAB format to reference to protocols used, with optionally use of certain protocol parameter values. For example, a Source may be transformed into a Labeled Extract by the subsequent application of a Extraction and Labeling protocol. ProtocolApplication is associated with and Edge that links input/output, e.g. Source to Labeled Extract. The order of the application of protocols can be set in order to be able to reconstruct the left-to-right order of protocol references in MAGE-TAB format. The FuGE equivalent to ProtocolApplication is FuGE:ProtocolApplication, however input/output is modeled using Edge.

MAGE-TAB 1.1 has the column ArrayDataFile and DerivedArrayDataFile.

An association to ArrayDataFile is typically instrumentation level data and self describing e.g. in the microarray domain an Affymetrix cel file. An association to DerivedArrayDataFile is typically derived data e.g. an Affymetrix CHP file.

Entities:

Identifiable (interface).

For modeling and implementation purposes, all objects in MAGE-TAB model that have an id and name inherit from identifiable. Other classes in the model can be specified as sub-classes, inheriting from Identifiable. Identifiable gives classes a unique identifier within the scope and a name that need not be unique. Also it is possible to add comments to any objects; in the MAGE-TAB format this is implied if a Comment[name] is added after/next to the elements that needs to be commented

OntologyTerm

A single entry from an ontology or a controlled vocabulary. If it is a simple controlled vocabulary, there may be no formal accession for the term. In these cases the local name should be repeated in both term and termAccession. If the term has a value, the OntologyIndividual will have a single DataProperty whose value was the value for the property. For instance, for an OntologyIndividual based on the MO ontology the attributes might be: The term would be what is usually called the local name in the Ontology, for instance 'Age'; The termAccession could be 'http://mged.sourceforge.net/ontologies/MGEDOntology.owl#Age' or a an arbitrary accession if one exists; The identifier is a unique identifier for individuals in the scope of the FuGE instance; The inherited name attribute should not be used; The ontologyURI of OntologySource could be 'http://mged.sourceforge.net/ontologies/MGEDOntology.owl". The OntologyTerm subclasses are instances of Ontology classes and properties, not the actual terms themselves. An OntologyIndividual, if based on an existing Ontology, can be considered a statement that can be validated against the referenced ontology. The subclasses and their associations are based on the Ontology Definition Model, ad/2005-04-13, submitted to the OMG as a response to RFP ad/2003-03-40, Copyright © 2005 DSTC Pty Ltd.

Investigation

Investigation is a high level object that represents information about a biological investigation. Ontology Terms are used to describe design type, quality control, replicate design. A title and description provide free text descriptions of the Investigation. Note that Investigation can be using one or more technologies such as Genotyping and Gene Expression. Version is an additional attribute of the 1.1 MAGE-TAB version and is included to represent the format version NOT the version of the Investigation. Investigation and Experiment are considered synonyms in this model, both are used interchangeably in the MAGE-TAB specification. A URI has been included in the model to refer to SDRF and ADF files that do exist locally. Example E-MTAB-506 ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/TABM/E-TABM-506/E-TABM-506.idf.txt .

Factor

Factor represents the investigators INTENDED variable within an Investigation. Example being in cancer studies, whether the subject has cancer or not is an intended variable, whereas the age difference between the subjects (although definitely variable) may be unimportant in the particular study design and shouldn't be reported as Factor. Typically this correlates with the design type of investigation. For example a design in which a disease versus normal is investigated is a disease state design and the corresponding Factor would be of type disease state. Factors have an association to FactorValue where the values are instantiated as ontology terms or measurements. An example of factor can be seen in E-MTAB-506 ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/TABM/E-TABM-506/E-TABM-506.idf.txt .

Person represents one or more people involved with an Investigation. This may include authors on a paper, lab personnel or PIs. Person has last name, firstname, mid initial, address, contact and email. A Person role is included to represent how a Person is involved with an investigation. For submission to repository purposes an allowed value is 'submitter' and the term is present in the MGED Ontology, an alternative use could represent job title. An Example from ArrayExpress is E-MTAB-506 ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/TABM/E-TABM-506/E-TABM-506.idf.txt. .

Publication

Publication is part of the Investigation package and is used to represent information about one or more publications related to an Investigation. The publication need not only be primary publication for an Investigation but may also represent other related information- though this use is less common. Publications have attributes of publications Authors and also DOI and Pubmed identifiers (when these are available). These are represented as OntologyTerms as in the MAGE-TAB model all 'xrefs' (cross references) for ontologies and accession numbers are handled generically. An example of a publication is available in an IDF file from ArrayExpress is experiment E-MTAB-506 ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/TABM/E-TABM-506/E-TABM-506.idf.txt.

Protocol

Protocol is a high level object that represents the details of protocols used during the investigation. The uses of Protocols to process BioMaterials and Data are referenced by ProtocolApplication (in the SDRF part of the format). Protocol has an association to OntologyTerm to represent the type of protocol. Protocols are associated with Hardware, Software and Parameters used in the Protocol. An example from ArrayExpress is E-MTAB-506 ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/TABM/E-TABM-506/E-TABM-506.idf.txt.

ArrayDesign

The ArrayDesign is used to represent the information about e.g. a microarray. The attributes are required to fulfill the MIAME conditions regarding surface type, polymer type etc and an association to ProtocolApplication is used to describe the details of Array production typically for self made rather than commercial arrays. The ArrayDesign is a high level object. ArrayDesign has associations to Features, Reporters and CompositeElements (previously called CompositeSequences in MAGE-OM 1.0) which describe layout of the ArrayDesign. ArrayDesign is only required for Array based experiments which use a traditional type microarray where layout and relationships of probes are important to detect layout effects.
There is no direct equivalent of ArrayDesign in FuGE, Protocol and/or Equipment is likely the nearest map as an Array specific extension was needed.

Edge

An Edge is a generic object that is used to describe the treatments between Materials and Data in an experiment (i.e. the Nodes of the experiment graph). An Edge can be annotated with ProtocolApplications using the reference from ProtocolApplication to Edge. It has no explicit equivalent in the MAGE-TAB format specification but acts as a container for chain of zero-or-more ProtocolApplications that can be added, e.g. between Source, Sample, Assay, etc. See example, E-MTAB-506 ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/TABM/E-TABM-506/E-TABM-506.idf.txt

ProtocolApplication

ProtocolApplications are used in MAGE-TAB format to reference to protocols used, with optionally use of certain protocol parameter values. For example, a Source may be transformed into a Labeled Extract by the subsequent application of a Extraction and Labeling protocol. ProtocolApplication is associated with and Edge that links input/output, e.g. Source to Labeled Extract. The order of the application of protocols can be set in order to be able to reconstruct the left-to-right order of protocol references in MAGE-TAB format.
