Abstract

One or more artifact drafts may be associated with each of a plurality of artifacts, each of the artifact drafts representing a state of the associated artifact at a point in time and one or more commands in a command stack that transformed the artifact draft'"'"'s parent into the artifact draft. Multiple traceability links and traceability vertices represent connections between the artifact drafts of the artifacts. A traceability link includes an edge between an artifact draft of an artifact and an artifact draft of another artifact. A module is operable to navigate through said one or more artifacts of the plurality of artifacts from a reference temporal point via the plurality of traceability links.

Claims

1. A system to view and manipulate artifacts at a temporal reference point, comprising:

one or more artifact drafts associated with each of a plurality of artifacts, each of said one or more artifact drafts representing a state of the associated artifact at a point in time and one or more commands in a command stack that transformed said each artifact draft'"'"'s parent into said each artifact draft;

a plurality of traceability links and traceability vertices representing connections between said one or more artifact drafts of the plurality of artifacts, wherein a traceability link includes an edge between an artifact draft of an artifact in the plurality of artifacts and an artifact draft of another artifact in the plurality of artifacts, said artifact draft of an artifact in the plurality of artifacts and the artifact draft of another artifact in the plurality of artifacts forming the traceability vertices, the traceability link created at least in response to automatically detecting an action performed within one artifact that automatically accesses said another artifact, without a user explicitly accessing said another artifact wherein said another artifact is automatically identified, wherein the traceability link comprises an indication at said one artifact as a consumer and a first link pointing to an offset and length in said one artifact'"'"'s content where the action occurred, and an indication at said another artifact as a producer and a second link pointing to an offset and length of said another artifact'"'"'s content that is accessed;

a processor; and

a module operable to execute on the processor and navigate through said one or more artifacts of the plurality of artifacts from a reference temporal point via the plurality of traceability links,

wherein the module is further operable to navigate across said one or more artifact drafts of different artifacts via the traceability links in response to an artifact draft being selected,

wherein the artifact draft is selectable by point in time,

wherein viewing the artifact draft that is selected enables viewing of all artifacts connected to the artifact draft that is selected in said all artifacts'"'"' states as said all artifacts'"'"' states were at points in time at which respective connection to the artifact draft that is selected was created,

wherein the artifact and said another artifact are different application program documents.

2. The system of claim 1, further including a server that stores said one or more artifact drafts and said plurality of traceability links and traceability vertices.

3. The system of claim 1, wherein the module is further operable to create said one or more artifact drafts and said plurality of traceability links and traceability vertices.

4. The system of claim 1, wherein said traceability links and traceability vertices are created automatically in response to an action being performed on said artifact draft of an artifact in the plurality of artifacts that accesses said artifact draft of another artifact in the plurality of artifacts.

5. The system of claim 1, wherein the module includes a user interface that enables a user to select said temporal reference point and present views of said artifact drafts.

6. The system of claim 5, wherein the module further presents said artifact drafts navigated starting from said temporal reference point via the user interface.

7. The system of claim 1, wherein the module is further operable to modify said one or more artifact drafts based on received commands.

8. The system of claim 1, wherein the module further includes an application interface via which one or more commands are received for manipulating said one or more artifact drafts.

9. The system of claim 1, wherein the module is further operable to create a new branch of artifact draft by creating a new artifact draft from an artifact draft that is not a most recent draft, wherein a starting state of the new branch of an artifact draft is an artifact'"'"'s state in a draft from which the new branch is created.

10. The system of claim 1, wherein said one artifact comprises an executable logic being authored with an authoring tool and said another artifact comprises an ontology employed by the authoring tool, the ontology that defines a word entered into the authoring tool in authoring the executable logic.

11. A computer readable storage medium storing a program of instructions executable by a machine to perform a method to view and manipulate artifacts at a temporal reference point, comprising:

receiving a command that edits a first artifact;

adding a time stamp to the command;

storing the command in a command stack;

storing a current state of the first artifact and the command stack as an artifact draft, wherein the first artifact has a plurality of artifact drafts associated with the first artifact; and

in response to detecting that the command comprises an action performed from the first artifact that accesses a second artifact, creating a traceability link between said artifact draft and a second artifact draft associated with said second artifact, wherein the traceability link comprises an indication at the first artifact as a consumer and a first link pointing to an offset and length in the artifact draft'"'"'s content where the action occurred, and an indication at the second artifact as a producer and a second link pointing to an offset and length of the second artifact'"'"'s content that is accessed, the second artifact draft corresponding to the second'"'"'s artifact current state as of a time of the action performed in the first artifact that accesses the second artifact, wherein the action that accesses the second artifact responsive to which the traceability link is created comprises at least an automated action that is not an explicit user action on the second artifact wherein the second artifact is automatically identified, the artifact draft and the second artifact draft forming traceability vertices, the second artifact having a plurality of second artifact drafts associated with the second artifact, wherein a user is enabled to traverse an artifact draft graph comprising said traceability vertices, wherein viewing a state of the first artifact enables the user to view all artifacts connected to the first artifact in their state as they were at points in time at which respective connection to the state of the first artifact was created,

wherein the artifact draft represents the current state of the first artifact at a point-in-time corresponding to the time stamp, and the command stack comprises one or more commands issued since initial creation of the artifact draft to the current state, wherein the artifact draft is editable until it is sealed and becomes a complete draft, and wherein a new child draft can be created based on the artifact draft that becomes complete,

wherein the artifact drafts are selectable by point in time,

wherein the first artifact and the second artifact are different application program documents.

12. The computer readable storage medium of claim 11, further including assigning the current state of the first artifact as a new artifact draft.

13. The computer readable storage medium of claim 11, wherein the steps are repeated for a plurality of artifacts, and wherein a plurality of artifact drafts and associated plurality of traceability links are generated for each of said plurality of artifacts.

14. The computer readable storage medium of claim 13, further including:

receiving a selected artifact draft, the selected artifact draft representing a temporal reference point;

searching the traceability links and traceability vertices to find one or more other artifact drafts linked to the selected artifact draft; and

presenting the selected artifact draft and said one or more other artifact drafts as of the same temporal reference point, if said one or more other artifact drafts exist.

15. The computer readable storage medium of claim 14, further including:

if said one or more other artifact drafts do not have time stamps corresponding to said temporal reference point,

selecting a command point from a command stack associated with said one or more other artifact drafts, that has a time stamp that is closest to the temporal reference point;

rewinding or replaying one or more commands in the command stack from said command point to generate a state of said one or more other artifacts; and

presenting the generated state of said one or more other artifacts.

16. The computer readable storage medium of claim 13, further including:

receiving a point in the command stack between two artifact drafts, the point in the command stack representing a temporal reference point;

choosing an artifact draft from the two artifact drafts that is closest temporally to the point in the command stack;

searching the traceability link and traceability vertices to find one or more other artifact drafts linked to the chosen artifact draft;

if said one or more other artifact drafts have time stamp corresponding to said temporal reference point, presenting said one or more other artifact drafts; and

if said one or more other artifact drafts do not have time stamp corresponding to said temporal reference point,

selecting a command point from a command stack associated with said one or more other artifact drafts, that has a time stamp that is closest to the temporal reference point;

rewinding or replaying one or more commands in the command stack from said command point to generate a state of said one or more other artifacts that is related to said point in the command stack between two artifact drafts; and

presenting the generated state of said one or more other artifacts.

17. The computer readable storage medium of claim 13, further including:

editing an artifact draft that is not a most recent artifact draft associated with an artifact; and

creating a new branch of artifact draft starting from the edited artifact draft.

18. The computer readable storage medium of claim 11, wherein said first artifact comprises an executable logic being authored with an authoring tool and said second artifact comprises an ontology employed by the authoring tool, the ontology that defines a word entered into the authoring tool in authoring the executable logic.
