If you mouseover the CoinSpark link you can see what kind of transaction it is.  In this case it's a Genesis transaction, so you (or somebody else) issued one unit of an asset to a CoinSpark address (which is just a wrapper around an underlying Bitcoin address).  If the issuer uploads the PDF contract and HTML file to the website path, the SparkBit wallet for the CoinSpark address will validate the asset and then it could be sent onto someone else.
