My MarkLogic database consists of a couple of sample documents in the folder "patents":
Each document looks like that:
{
"patent": {
"title": "Airless SCUBA diving",
"inventor": "Greg",
"description": "Diving pill that provides airless SCUBA diving for up to 1 hour"
}
}
I am trying to create a template:
const tde = require ('/MarkLogic/tde');
const inventionsTemplate = xdmp.toJSON(
{
'template':{
'context':'patent',
'directories':["patents", "another_patents"],
'rows':[
{
'viewName':'inventions',
'columns':[
{
'name':'title',
'scalarType':'string',
'val':'../title',
'nullable':true
},
{
'name':'inventor',
'scalarType':'string',
'val':'../inventor',
'nullable':true
},
{
'name':'description',
'scalarType':'string',
'val':'../description',
'nullable':true
}
]
}]
}
}
);
tde.templateInsert('/templates/inventionsTemplate.json', inventionsTemplate);
But getting an error:
[javascript] TDE-INVALIDTEMPLATE: (err:FOER0000) tde.templateInsert('/templates/inventionsTemplate.json', inventionsTemplate); -- Invalid TDE template: TDE-INVALIDTEMPLATENODE: Invalid extraction template node: fn:doc("")/template/array-node("rows")/object-node()

What is the proper syntax for creating MarkLogic template driven extraction in my case? Am I missing some preparation step before inserting TDE?
Your row is missing a schemaName
property.
If you add that to the object in the rows
array it will validate and insert.
'rows':[
{
'schemaName':'patents',
'viewName':'inventions',
'columns':[
The documentation could probably be improved to indicate which properties, such as schemaName
and viewName
are required and which are optional, such as view-layout
.
