System and method for offline editing of data files
View Patent ↗A system and method that enables a user to edit a data file offline is described. This system and method can enable a user to edit a data file without the user having to discover or deploy a solution application governing the data file. For security, this system and method can deploy a solution application within a sandbox, thereby limiting the operations the solution application can perform.
1. A computer-implemented method comprising:
receiving input to open a data file having a solution;
discovering, without user interaction, the solution in an offline memory source;
deploying, without user interaction, the solution;
opening the data file effective to enable a user to edit the data file; and
prior to receiving the input to open the data file:
discovering a solution identifier in a prior data file governed by the solution;
computing a special name from the solution identifier;
naming a folder of an offline memory source with the special name; and
downloading the solution from an online memory source into the folder.
2. The method of claim 1 , wherein discovering the solution is performed using the special name.
3. A computer-implemented method comprising:
receiving input to open a data file having a solution;
discovering, without user interaction, the solution in an offline memory source;
deploying, without user interaction, the solution;
displaying a representation of the data file;
prior to deploying the solution, updating the solution discovered in the offline memory source with a newer solution, wherein updating the solution includes:
comparing a time stamp of the solution with a time stamp of the newer solution; and
replacing the solution with the newer solution.
4. A computer-implemented method comprising:
receiving input to open a data file;
discovering a solution identifier in the data file;
computing a special name corresponding to the solution identifier;
searching local memory for the special name; and
installing a solution found in a folder having the special name, wherein the solution identifier is a URL.
5. A computer-implemented method comprising:
receiving input to open a data file;
discovering a solution identifier in the data file;
computing a special name corresponding to the solution identifier;
searching local memory for the special name; and
installing a solution found in a folder having the special name, wherein the solution identifier is a URN.
6. A computer-implemented method comprising:
receiving input to open a data file;
discovering a solution identifier in the data file;
computing a special name corresponding to the solution identifier;
searching local memory for the special name; and
installing a solution found in a folder having the special name, wherein the local memory is a cache.
7. A computer-implemented method comprising:
receiving input to open a data file;
discovering a solution identifier in the data file;
computing a special name corresponding to the solution identifier;
searching local memory for the special name; and
installing a solution found in a folder having the special name, wherein computing the special name is performed with a one-way hash.
8. The method of claim 7 , wherein the one-way hash is an MD5 hash.
9. A system comprising:
a display having a screen capable of displaying icons or text representing a data file;
a user-input device capable of enabling a user to select the data file;
a network interface capable of communicating with a communications network to download a data file's solution application;
a computer capable of executing applications and communicating with a local memory source to store the data file's solution application; and
a document manager application executable on the computer and configured to discover and deploy the data file's solution from the local memory source without user interaction.
10. The system of claim 9 , wherein the document manager application is further capable of silently deploying the data file's solution within a sandbox.
