Display metadata values in component

RHEL 5.8
TS/LS 7.3.1

I'm new to component development and have a question about displaying metadata/extended attributes of a file using a component.

What I'm trying to do is modify a clone of the out-of-the box "Dynamic Targeted Image List" component, which uses the Content Retriever to display a list of images based on metadata, to also display the image's title and description metadata values.

Is this doable? Can someone provide a little direction? Thanks!

Here's a snippit of the component

It's doable, but it has more to do with the data coming back from your LSCS query than it does the rendering (xsl). Start with a <xsl:copy-of select="/Properties/Data/Result" > clause in your XSL to see what data is actually coming back from the query. Then, your query to retrieve what you're looking for before rendering it nicely. The LSCS tech reference (in the TS 7.1 folder) should assist with your query, assuming the sample Java External you're using allows you that flexibility (I didn't check). It could be that you'll need to roll your own.

Thanks for the reply. Taking your advice I inserted [xsl:copy-of select="/Properties" /] in the XSL section of the component. Following is the relevent snippet.

<metadatafield name="ast_expiration_date">
<metadatafield name="ast_creation_date">2012-11-26 23:48:51

What's interesting with the results is that only a very small portion of the file's extended attributes are returned via the Content Retriever. Is this due to how the Content Retriever class is written or more of a LSCS indexing issue? Any advise on returning additional metadata (Title & Summary) without modifing the class or creating and external component? Thanks!

I just queried LSCS directly and do see the additional metadata fields in the result, so for some reason the Content Retriever is not returning all of the metadata fields. Does anyone know if this is simply a limitation of the class or if there's a configuration to update?

Looks like the Content Retriever class can return additional metadata fields by passing the field names as params to the class, but no where in the doc mentions how to do this. I'm thinking maybe the param's are specified in the Actions Verbalization file but I haven't found anything to support this.

Any ideas?

// retrieve additional metadata based on the input
// available through TaggedMetadata Parameter
String taggedMetadataInput = (additionalParameterMap !=
null) ? (additionalParameterMap.get(TAGGED_METADATA)) : "";

If you trace that backwards in the code, you can see that it comes from the <ActionParameters> in your component's Rule datum. Add a <Param Name="TaggedMetadata"> element (whether in the component definition or by editing the properties of the component on your page) with a comma-delimited list of metadata fields you need, and that should do it.

Thanks Rick!!! That worked!!!
