Examples

Assuming a postgres table that contains JPEG images in the content column:

...

Code Block
languagexml
<data:blob id="example" acl="private">
	<datasource>postgres</datasource>
	<table>blob_test</table>
	<key>pid</key>
	<column>content</column>
	<contentType>image<contenttype>image/jpg</contentType>contenttype>
	<fallbackurl>/resources/images/missing.jpg<fallbackurl>
</data:blob>

The images can then be references using the URL http://weave.hostname/weave/data/blob/example/1234 (assuming there is a row that has the value 1234 in the pid column)
