Exhibit uses a "graph structured" data model, of entities that can be
connected to other entities in arbitrary shapes. Any hierarchically
structured data can easily be represented in a graph structured
model---it's just graph structured data without cycles. But I can see
the appeal/convenience of wanting use a hierarchical representation in
the json file as well. This does raise one problem/issue.
Exhibit does use a graph representation internally, based on every item
having a label or id that can be referenced to point to the item. If
you load an item without a label or id, exhibit makes one up.
So, in loading the hierarchical data, one needs to extract (or generate)
the label/id of the child item, and represent the child connection by
inserting a reference to the child label into the database.
I'd be happy to take a pull request implementing this.

That sounds good.
But requires some JSON preprocessing.
Could it be smarter to patch the _loadItems function in Exhibit so it
automatically adds in the database any nested objects it meets?

Making the nested objects first class items would pollute my facets, no?
No, because you'll work with your default collection. Look at the
collection's definition.
(In my case, the nested objects are really nested. They are a part of an item,
not item themselves).

Maybe you should use a normalized json:
{
"items": [{
"interests": ["xx", "yy"],
"label": "toto",
"type": "x",
"a": "1.1",
"id": "1"
},
{ "b": "1", "label": "tata", "id": "1.1", "type": "y" }],
"properties": {
"a": {
"valueType": "item"
}
}
}
And create a default collection: <div
data-ex-role="exhibit-collection" data-ex-item-types="x"></div>
I've never used a nested structure in the json data.

Yes.
I made them available at those URLs:
http://search.datao.net/test/index.html
http://search.datao.net/test/index2.html
The first one fails to display the .a.b for an item.
The second one displays fine the .label of an item

Are you exhibit example online? It's easier to test it.

Hi everyone.
I need some help about lens configuration in Exhibit 3.
My items have a nested structure where the property "a"
contains an object with a property "b":
{ "items": [
{
"label":"toto",
"type":"x",
"a": {"b":"1"}
}
]
}
I wish I could define my item thumbnail to be its .a.b value wrapped in a
div.
Such HTML does not seem to work in that case:
<div data-ex-role="viewPanel">
<div data-ex-role="view"
data-ex-view-class="Thumbnail"
data-ex-show-all="true"
data-ex-paginate="true"
<table data-ex-role="lens" class="itemThumbnail" style="display: none;">
<tr>
<td style="vertial-align:bottom" class="itemThumbnail-thumbnailContainer">
<div style="position: relative">
<div
data-ex-content=".a.b"/>
</div>
</td>
</tr>
</table>
</div>
</div>
I get nothing displayed in my view panel.
What kind of syntax must be used to display a nested valye inside a <div>
?
Any help is welcome!
PS: are there some Exhibit examples managing such nested data structures?
