MBException - reviseAssetMetadata

I'm having trouble using the reviseAssetMetadata() method within the Java API's. Under a certain folder, I'm trying to update certain fields but I'm having some trouble. Since I've had no luck updating individual fields, for the sake of testing, I am trying to pass the original (unchanged) ArrayOFMetadata object with the Asset ID, to the reviseAsset method. Even passing the unchanged ArrayOFMetadata object, I continue to get an AxisFault error.

Here is the error I am getting when I call the reviseAssetMetadata() method:
AxisFault

Here's the snippet of code where the error is happening:
// snippet start
if(cont.getMName().equals("POS"))
{
logger.info("name: " + cont.getMName());
logger.info("cid: " + cont.getMID());

// get Assets for this Container (folder)
ArrayOfMBAsset arrayAsset = mMediaBinServer.getAssetList(cont.getMID());
if(arrayAsset.getMBAsset() != null)
{
// this is the true Array
MBAsset[] asset = arrayAsset.getMBAsset();
for (int j = 0; j < asset.length; j++)
{
MBAsset mbAsset = mMediaBinServer.getAsset(asset.getMID());
ArrayOfMBMetadata arrMetadata = mbAsset.getMetadata();
logger.info("ArrayOFMetadata&colon; " + arrMetadata);
if( arrMetadata != null)
{
logger.info("I've got the ArrayOFMBMetadata!");
//This is the true array
MBMetadata[] metadata = arrMetadata.getMBMetadata();
logger.info("length: " + metadata.length);
}
mMediaBinServer.reviseAssetMetadata(mbAsset.getMID(),arrMetadata);
}
}
}
// end snippet

The version of MediaBin is: 4.5. Any suggestions or examples would be appreciated.

Thanks,
Jay

You cannot use the Metadata array returned from GetAsset in a call to ReviseAssetMetadata because it includes metadata values that are not editable....e.g. Asset Type, Resolution, Dimensions. In addition, this list is made to be "display friendly" by switching out any value list metadata values into their display string equivalents; when you revise the metadata you will want to use the true values....see the method GetEditableMetadata for more details about metadata values and formats.

If you could post a snippet of the code that tries to revise individual values, I might be able to see where you are getting snagged.

Here's the snippet of code...

if(cont.getMName().equals("POS"))
{
logger.info("name: " + cont.getMName());
logger.info("cid: " + cont.getMID());

// get Assets for this Container (folder)
ArrayOfMBAsset arrayAsset = mMediaBinServer.getAssetList(cont.getMID());
if(arrayAsset.getMBAsset() != null)
{
// this is the true Array
MBAsset[] asset = arrayAsset.getMBAsset();
for (int j = 0; j < asset.length; j++)
{
MBAsset mbAsset = mMediaBinServer.getAsset(asset.getMID());
//MBAsset mbAsset = arrayAsset.getMBAsset(j);
if(mbAsset.getMName().equals("BSR_TEST.pdf"))
{
ArrayOfMBMetadata arrMetadata = mbAsset.getMetadata();
if( arrMetadata != null)
{
//This is the true array
MBMetadata[] metadata = arrMetadata.getMBMetadata();
for (int k = 0; k < metadata.length; k++)
{
if(metadata.getMName().equals("Item Description"))
{
ArrayOfMBMetadata arr2 = new ArrayOfMBMetadata();
MBMetadata mb2 = metadata;
mb2.setMValue("Testing...");
arr2.setMBMetadata(k,mb2);
mMediaBinServer.reviseAssetMetadata(mbAsset.getMID(),arr2);
}
}
}
}
}
}
}

What I'm trying to do is as follows: I'm going through all containers (code not shown above) looking for folders named "POS". Once I find a container named "POS", I'm then going through each Asset getting it's Metadata (for the sake of testing, I'm looking for a particular File and Metadata value). I'd like to then update certain Metadata fields (Filename, Original Filename, Item Description, etc..)...

I am unfamiliar with the Mediabin product/API's so if there is a better way to accomplish this, I would appreciate any input.

Thanks!

The easist way to modify metadata is to build the metadata array with just the metadata you wish to add or modify. I've attached a sample function that illustrates how to add three new pieces of metadata. I've also included the custom metadata used in the sample as xml files....you can import them into your MediaBin server using the native Windows client, the web client or by using the web service method ImportMetadataDefinition.

Also, the web service method GetAssetIDList is quicker and more efficient than GetAssetList since all you really need are the ids of the assets.

Thanks for your examples, I've got most of fields updated now... I do have one more question. We want to rename the field named 'Name', which happens to be a Read-Only (non editable) field. When trying to update through the API's, we get an Exception, which makes sense. My confusion is this: through the MediaBin Client, we are able to right click on the image and select 'Rename', and we successfully rename the image. How is this different than doing it through the API's. Isn't it the same field or is there a display name than is different than what I'm trying to modify?

Thanks!

An asset's name cannot be changed via a metadata edit....the client apps as well as the API use a separate method to change the name. The webservice method is called ChangeAssetName ( changeAssetName in Java ).
