What does it mean?

1. The Message

{md5 => fb08f9a7d3fafaf2789750c8e7a9dfaf, owner => DTC:D9cavkk1ZmaWqxfuYjWPbbo36SFqzi45ow, inputtx => FirstIssue, previousowner => DTC:D9cavkk1ZmaWqxfuYjWPbbo36SFqzi45ow, idop => CB1}

transfers the ownerhip of the asset with md5

fb08f9a7d3fafaf2789750c8e7a9dfaf

from the owner

DTC:D9cavkk1ZmaWqxfuYjWPbbo36SFqzi45ow

to the owner

DTC:D9cavkk1ZmaWqxfuYjWPbbo36SFqzi45ow

2. This Message is signed by the Previous Owner with the private key corresponding to

DTC:D9cavkk1ZmaWqxfuYjWPbbo36SFqzi45ow

because only the Previous Owner can transfer the asset to a New Owner
3. Everyone can check the Previous Owner Sign

Hx0FS8sOJ5zOnM7sLEzBKJX4q9legn1U/BI43TB9Zxa/hcbe79QfGdpYfSz/FW2LkxG3yeOIj+pz4hW42iMOnJY=

against the Message and the address

DTC:D9cavkk1ZmaWqxfuYjWPbbo36SFqzi45ow

4. Then the previous owner sign is appended to the message obtaining the new message

{{md5 => fb08f9a7d3fafaf2789750c8e7a9dfaf, owner => DTC:D9cavkk1ZmaWqxfuYjWPbbo36SFqzi45ow, inputtx => FirstIssue, previousowner => DTC:D9cavkk1ZmaWqxfuYjWPbbo36SFqzi45ow, idop => CB1}, prevownersign => Hx0FS8sOJ5zOnM7sLEzBKJX4q9legn1U/BI43TB9Zxa/hcbe79QfGdpYfSz/FW2LkxG3yeOIj+pz4hW42iMOnJY=}

5.This new message is signed By Bytestamp with the private key corresponding to the DTC address D8GafEsbyssg4TQN71KTbd8QdRg846MxCQ , that is on ByteStamp Web Site and also saved in the Datacoin Blockchain in transaction 78c8b327930ec9ec4e280801e2ebba190add5bcbeca295dba9992d5e2cb455bb
6. Then the Bytestamp sign

INkNtXDtfAiJTv8Cq2foJUpUtofPHmCb/G+f1QJqXeIEtVm93k4Nazg/1iGbAQqaCyPRUqp2vUFPbFJQJerEr20=

is appended to the message togheter with the Hash of the Previous Transaction containing a data Asset:

1a6dda8de4e7593ee70050ad4e5860cf
7.So we have a new message

{{{{md5 => fb08f9a7d3fafaf2789750c8e7a9dfaf, owner => DTC:D9cavkk1ZmaWqxfuYjWPbbo36SFqzi45ow, inputtx => FirstIssue, previousowner => DTC:D9cavkk1ZmaWqxfuYjWPbbo36SFqzi45ow, idop => CB1}, prevownersign => Hx0FS8sOJ5zOnM7sLEzBKJX4q9legn1U/BI43TB9Zxa/hcbe79QfGdpYfSz/FW2LkxG3yeOIj+pz4hW42iMOnJY=}, bytestampsign => INkNtXDtfAiJTv8Cq2foJUpUtofPHmCb/G+f1QJqXeIEtVm93k4Nazg/1iGbAQqaCyPRUqp2vUFPbFJQJerEr20=}, prevhash => 1a6dda8de4e7593ee70050ad4e5860cf}

on which is calculated an hash, just as a blockchain works (hashcash)
8. This hash

4377eda938b27684364d2fd491246a34

is appended to the Message and we have the final Message

ASSET:{{{{{md5 => fb08f9a7d3fafaf2789750c8e7a9dfaf, owner => DTC:D9cavkk1ZmaWqxfuYjWPbbo36SFqzi45ow, inputtx => FirstIssue, previousowner => DTC:D9cavkk1ZmaWqxfuYjWPbbo36SFqzi45ow, idop => CB1}, prevownersign => Hx0FS8sOJ5zOnM7sLEzBKJX4q9legn1U/BI43TB9Zxa/hcbe79QfGdpYfSz/FW2LkxG3yeOIj+pz4hW42iMOnJY=}, bytestampsign => INkNtXDtfAiJTv8Cq2foJUpUtofPHmCb/G+f1QJqXeIEtVm93k4Nazg/1iGbAQqaCyPRUqp2vUFPbFJQJerEr20=}, prevhash => 1a6dda8de4e7593ee70050ad4e5860cf}, hash => 4377eda938b27684364d2fd491246a34}

with the initial tag

ASSET:

which identifies the data as an Asset transaction
9. This final Message is stored in the Datacoin BlockChain, so nobody can change an ownership transfer once it happened.
_
Note1 We transfer the ownership of the file which has a unique MD5 previously uploaded on ByteStamp. Since the file can be or can not to be public, we can transfer the ownership also without knowing what the asset is
Note2 Yes, we can also transfer assets accross Datacoin and Bitcoin addresses.
