TMF - a tutorialPart 3: Designing (schemas and)

filters

TMF - Terminological Markup Framework

Laurent Romary - Laboratoire Loria

General principles

Terminological information interchange– Three components:

• Source TDB1

• Target TDB2

• Terminological interchange format– A specific TML (DXLT, Geneter)

TDB1 TDB2

TML

Important notice

– GMT is not a TML• A too abstract format

– Uncontrolled recursivity (‘ struct ’ element)

– Uncontrolled content (‘ feat ’ and ‘ annot ’)

• Necessity to provide a schema to check interchanged data

– Precise list of datacategory

– Precise definition of format

– GMT is here to provide conceptual simplicity

Designing filters

TML to GMT

General principles

Just for your information– The creation of the filters can be automatized

Basic processes– Reduction of expansion trees– Mapping elements and attributes to the

corresponding data categories

Reducing expansion trees

Example• DXLT (Martif) sub-tree

<ntig><!-- some general information associated with the term --><termGrp>

<!-- term related information --></termGrp>

</ntig>

• GMT<struct type="TS"><!-- some features -->

</struct>

Element mapping

Example• DXLT (Martif)

<definition>Bla, bla, bla etc.</definition>

• GMT<feat type="definition">Bla, bla, bla etc.</feat>

Structural elements

Generating a GMT ‘ struct ’ element

<xsl:template match="termEntry"><xsl:element name="struct">

<xsl:attribute name="type">TE</xsl:attribute>

<xsl:apply-templates select="@*|node()"/></xsl:element>

</xsl:template>

Features

Generating a GMT‘ feat ’ element» (style=Attribute)

<xsl:template match="@id"><xsl:element name="feat">

<xsl:attribute name="type">iso12620-identifier</xsl:attribute>

<xsl:value-of select="."/></xsl:element>

</xsl:template>

Features

Generating a GMT‘ feat ’ element» (style=Element)

<xsl:template match="term"><xsl:element name="feat">

<xsl:attribute name="type">iso12620-term</xsl:attribute>

<xsl:apply-templates/></xsl:element>

</xsl:template>

Features

Generating a GMT‘ feat ’ element» (style=TypedElement)

<xsl:template match="descrip[@type='subjectField']"><xsl:element name="attr">

<xsl:attribute name="type">SubjectField</xsl:attribute>

<xsl:apply-templates/></xsl:element>

</xsl:template>

A two phase process

List the various Data Categories used in the TDB– Relate them to existing registries (e.g. iso 12620),

cf. http://salt.loria.fr/public/salt/DCQuery.html

Identify the underlying organization of the TDB– Relate it to the Meta-model– Anchor the DatCat where they actually occur

Simple rules

Using XSL locality

<xsl:template match="CM"> <feat type="classificationCode-12620A.4.2"> <xsl:apply-templates/> </feat></xsl:template>

Introducing specific levels

Necessity to combine structure and content

<xsl:template match="VE"> <struct type="TS"> <feat type="term-12620A.1"> <xsl:apply-templates/> </feat> </struct></xsl:template>

Default rule

Useful for keeping track of unmapped data categories

<xsl:template match="*"> <feat> <xsl:attribute name="type">

<xsl:value-of select="name()"/></xsl:attribute>

<xsl:apply-templates/> </feat></xsl:template>
