As you know,we can export objects(souce,target,mapping....) from informatica repository. If you are familiar with their the XML structure,you can easily use DOM to create or edit them.

Note: Informatica build-in DTD file is named "powrmart.dtd",you can find them on it's installed directory and you may need this DTD file when you use DOM.

Let's walk through general structure.

Common Nodes:

<POWERMART>//created date and repository version

<REPOSITORY>//repository name,version,codepgae and database type

<FOLDER>//name,group,owner,shared,description,permissions AND unique ID(UUID)

//All all kinds of objects have these three parent nodes. Usually we only care about repository name and folder name

Nodes of source:

<SOURCE>//database type,database name,name,etc

//if it's flat file source,you will have this node

[<FLATFILE>//codepage,delimiter,...]

<ALBEATTRIBUTE>//what did you set in property tab

<SOURCEFIELD>//one node represents one port,and you can eidt port here. Note: PHYSICALLENTH is an accumulative attribute.(take care of it)

<MetaDATAEXTENSION>//Meta data

Nodes of target:(similar with source)

<TARGET>

[<FLATFILE>]//codepage,delimiter,...

<TARGETFIELD>//one node represents one port

<TALBEATTRIBUTE>//what did you set in property tab

<MetaDATAEXTENSION>//Meta data

Nodes of mapping:

<SOURCE>//see above

<TARGET>//see above

<MAPPING>

<TRANSFORMATION>//type decide what it is in the mapping,such as "sourc qualifier","filter"

<TTRASFORMFIELD>

<TABLEATTRIBUTE>//what you set in the corresponding property tab

<INSTANCE>//create all instances for mapping form all definitions(source,transformation...)

<CONNECTOR>//one connector represent one link(come from who,arrive at where)

<TARGETLOADORDER>//define the loading sequence if existed multiple targets.

Nodes of workflow:

<WORKFLOW>

<SCHEDULER>//define scheduler

<TASK>//type decide what kind of task it is,such as "start","assignment',etc

<SESSION>//mapping name,reusalbe...

<SESSTRANSFORMATIONINST>//transformation instance in the session,e.g. source,target

<CONFIGREFERENCE>//session configuration

<SESSIONEXTENSION>//define properties for each transformation instance,e.g. source,target

<ATTRIBUTE>//What you set in session property tab

<TASKINSTANCE>//create all instances for workflow form all definitions(start,assignment,session...)

<WORKFLOWLINK>//one node represent one link in workflow

<WORKFLOWVARIABLE>//define workflow variables

<ATTRIBUTE>////What you set in workflow property tab
