Abstract

The invention relates to a method implemented by a first device (DV1) cooperating with a cloud (CL) of at least one server for resolving a synchronization conflict over different versions of a document object comprising at least one content file and one object descriptor file (ODF1). The method comprising obtaining a first version of the document object; performing a first synchronization phase comprising sending the first version (ODF1) of the object descriptor file, independently of the first version of the content file, to the cloud (CL); performing a second synchronization phase for resolving the conflict by re-sending the first version (ODF1) of the object descriptor file of the first device (DV1) to the cloud (CL); performing a third synchronization phase subsequent to the second synchronization phase, comprising sending the first version of the content file to the cloud (CL) for storing said first version of content file.

Dependent claims

A computer implemented method, implemented by a first device (DV1), for synchronizing different versions of a document object (DO1, DO2) in cooperation with a cloud (CL), wherein each version of said document object comprises at least one content file and one object descriptor file, said content file comprising a content and said object descriptor file comprising at least one object descriptor defining said content, said method comprising:

a) obtaining (S10) a first version (DO1) of the document object comprising a first version (CF1) of the content file and a first version (ODF1) of the object descriptor file, said first version of the object descriptor file comprising a first object descriptor in association with a first timestamp;
b) sending (S16) the first version of the object descriptor file, independently of the first version of the content file, to the cloud for causing said cloud to store said first version of the object descriptor file;
c) performing a first synchronization phase (S18-S22) comprising:
c1) checking (S18) a second timestamp comprised in a second version (ODF2) of the object descriptor file currently stored in the cloud;
c2) if the first timestamp of the first version (ODF1) of the object descriptor file stored by the first device is later than the second timestamp of the cloud checked in c1), detecting a first document synchronization conflict;
and
c3) resolving said first synchronization conflict by re-sending (S22) the first version (ODF1) of the object descriptor file to the cloud for causing said cloud to store said first version of the object descriptor file.

A method, implemented by a first device (DV1), for managing different versions of a document object (DO1, DO2) in cooperation with a cloud (CL), wherein each version of said document object comprises at least one content file and one object descriptor file, said content file comprising a content and said object descriptor file comprising at least one object descriptor defining said content, wherein said object descriptor file comprises a version history, said method comprising:

a) storing (S10) a first version of the document object comprising a first version (CF1) of the content file and a first version (ODF1) of the object descriptor file, said first version of the object descriptor file comprising a first version history (H1) defining at least one previous version of said document object on which basis the first version of the document object has been created;
b) retrieving a second version history (H2) comprised in a second version (ODF2) of the object descriptor file currently stored as part of a second version of the document object in the cloud, said second version history defining at least one previous version of said document object on which basis the second version of the document object has been created;
c) performing a comparison of the first and second version histories (H1, H2) to determine whether any of the first and second versions (DO1, DO2) of the document object originates from the other;
d) if it is detected, based on the comparison c), that the first version (DO1) of the document object originates from the second version (DO2) of the document object while the second version (DO2) of the document object does not originate from the first version (DO1) of the document object, sending the first version (CF1) of the content file to the cloud, independently of the first version of the object descriptor file, to cause the cloud to store said first version of the content file.
