What does it mean?

1. The Message

{md5 => 1c3a2b82e87314e978d0b635d4f1d3a2, owner => DTC:DKCuFxwHwpRsq3jP8w3PT3s2TKqPP29ZJU, inputtx => FirstIssue, previousowner => DTC:DKCuFxwHwpRsq3jP8w3PT3s2TKqPP29ZJU, idop => AG1}

transfers the ownerhip of the asset with md5

1c3a2b82e87314e978d0b635d4f1d3a2

from the owner

DTC:DKCuFxwHwpRsq3jP8w3PT3s2TKqPP29ZJU

to the owner

DTC:DKCuFxwHwpRsq3jP8w3PT3s2TKqPP29ZJU

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

DTC:DKCuFxwHwpRsq3jP8w3PT3s2TKqPP29ZJU

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

HzDprpoCzvee4+7jTRo6qDrypGMPnkdZbHlmF+yitsHhMYKvsvoCN457YNdopzihPnF3hrG4eXjWNFI2035YFIM=

against the Message and the address

DTC:DKCuFxwHwpRsq3jP8w3PT3s2TKqPP29ZJU

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

{{md5 => 1c3a2b82e87314e978d0b635d4f1d3a2, owner => DTC:DKCuFxwHwpRsq3jP8w3PT3s2TKqPP29ZJU, inputtx => FirstIssue, previousowner => DTC:DKCuFxwHwpRsq3jP8w3PT3s2TKqPP29ZJU, idop => AG1}, prevownersign => HzDprpoCzvee4+7jTRo6qDrypGMPnkdZbHlmF+yitsHhMYKvsvoCN457YNdopzihPnF3hrG4eXjWNFI2035YFIM=}

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

H3JKSII4JolOvvBDY1uS8ZxPJltzDuwz+mSxucjxLSTYQqNcP6wbIUkhQvgZo553abChjBWmvWplxPJQFdSo+BM=

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

738968bc25b219ab69def0dda8c83ae4
7.So we have a new message

{{{{md5 => 1c3a2b82e87314e978d0b635d4f1d3a2, owner => DTC:DKCuFxwHwpRsq3jP8w3PT3s2TKqPP29ZJU, inputtx => FirstIssue, previousowner => DTC:DKCuFxwHwpRsq3jP8w3PT3s2TKqPP29ZJU, idop => AG1}, prevownersign => HzDprpoCzvee4+7jTRo6qDrypGMPnkdZbHlmF+yitsHhMYKvsvoCN457YNdopzihPnF3hrG4eXjWNFI2035YFIM=}, bytestampsign => H3JKSII4JolOvvBDY1uS8ZxPJltzDuwz+mSxucjxLSTYQqNcP6wbIUkhQvgZo553abChjBWmvWplxPJQFdSo+BM=}, prevhash => 738968bc25b219ab69def0dda8c83ae4}

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

4f4fef5e87047cb2d09e8f80f784ec4e

is appended to the Message and we have the final Message

ASSET:{{{{{md5 => 1c3a2b82e87314e978d0b635d4f1d3a2, owner => DTC:DKCuFxwHwpRsq3jP8w3PT3s2TKqPP29ZJU, inputtx => FirstIssue, previousowner => DTC:DKCuFxwHwpRsq3jP8w3PT3s2TKqPP29ZJU, idop => AG1}, prevownersign => HzDprpoCzvee4+7jTRo6qDrypGMPnkdZbHlmF+yitsHhMYKvsvoCN457YNdopzihPnF3hrG4eXjWNFI2035YFIM=}, bytestampsign => H3JKSII4JolOvvBDY1uS8ZxPJltzDuwz+mSxucjxLSTYQqNcP6wbIUkhQvgZo553abChjBWmvWplxPJQFdSo+BM=}, prevhash => 738968bc25b219ab69def0dda8c83ae4}, hash => 4f4fef5e87047cb2d09e8f80f784ec4e}

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.
