Automated dereferencing of electronic communications for archival
Various methods and systems for automatically obtaining documents that are referenced by an electronic communication, such as an email or instant message, for archival are disclosed. One method involves searching at least a portion (e.g., the header and/or body) of an electronic communication for a reference to a document and, in response to detecting the reference, automatically obtaining an electronic copy of the document. The electronic copy of the document can then be archived.
1. A method comprising:
detecting an archival of an electronic communication;
searching at least a portion of the electronic communication for a reference to a document, wherein
the document is not included in the electronic communication;
determining that a copy of the document is not currently being maintained as part of the archival of the electronic communication;
in response to the determining, automatically obtaining, using a processor, an electronic copy of the document from a location identified by the reference;
archiving the electronic copy of the document as an archived electronic copy of the document; and
retrieving the electronic communication and the archived electronic copy of the document at a time when the document is no longer available at the location identified by the reference.
2. The method of claim 1 , comprising:
locally storing the electronic copy of the document.
3. The method of claim 1 , wherein
the electronic communication comprises one of: an electronic document, an email message, and an instant message.
4. The method of claim 1 , further comprising:
searching at least a portion of the electronic copy of the document for a second reference to a second document; and
automatically obtaining an electronic copy of the second document, in response to detecting the second reference.
5. The method of claim 1 , further comprising:
modifying the electronic communication, wherein
subsequent to being modified, the electronic communication comprises the electronic copy of the document.
6. The method of claim 1 , further comprising:
modifying the electronic communication, wherein
subsequent to being modified, the electronic communication comprises a pointer to a storage location storing the electronic copy of the document.
7. The method of claim 1 , further comprising:
accessing a policy prior to searching a particular electronic communication, wherein
the policy indicates whether the particular electronic communication should be searched for any references to documents.
8. A system comprising:
a processor; and
a memory, wherein the memory stores program instructions executable by the processor to:
detect an archival of an electronic communication;
search at least a portion of the electronic communication for a reference to a document, wherein
the document is not included in the electronic communication;
determine that a copy of the document is not currently being maintained as part of the archival of the electronic communication;
in response to a determination that the copy of the document is not currently being maintained as part of the archival of the electronic communication, automatically obtain an electronic copy of the document from a location identified by the reference;
archive the electronic copy of the document as an archived electronic copy of the document; and
retrieve the electronic communication and the archived electronic copy of the document at a time when the document is no longer available at the location identified by the reference.
9. The system of claim 8 , wherein the program instructions are further executable by the processor to:
locally store the electronic copy of the document.
10. The system of claim 8 , wherein the program instructions are further executable by the processor to:
search at least a portion of the electronic copy of the document for a second reference to a second document; and
automatically obtain an electronic copy of the second document, in response to a detection of the second reference.
11. The system of claim 8 , wherein the program instructions are further executable by the processor to:
access a policy prior to searching a particular electronic communication, wherein
the policy indicates whether the particular electronic communication should be searched for any references to documents.
12. A non-transitory computer readable storage medium comprising program instructions executable to:
detect an archival of an electronic communication;
search at least a portion of the electronic communication for a reference to a document, wherein
the document is not included in the electronic communication;
determine that a copy of the document is not currently being maintained as part of the archival of the electronic communication;
in response to a determination that the copy of the document is not currently being maintained as part of the archival of the electronic communication, automatically obtain an electronic copy of the document from a location identified by the reference;
archive the electronic copy of the document as an archived electronic copy of the document; and
retrieve the electronic communication and the archived electronic copy of the document at a time when the document is no longer available at the location identified by the reference.
13. The non-transitory computer readable medium of claim 12 , wherein the program instructions are further executable to:
locally store the electronic copy of the document.
14. The non-transitory computer readable medium of claim 12 , wherein the program instructions are further executable to:
search at least a portion of the electronic copy of the document for a second reference to a second document; and
automatically obtain an electronic copy of the second document, in response to a detection of the second reference.
15. The non-transitory computer readable medium of claim 12 , wherein the program instructions are further executable to:
modify the electronic communication, wherein
subsequent to being modified, the electronic communication comprises the electronic copy of the document.
16. The non-transitory computer readable medium of claim 12 , wherein the program instructions are further executable to:
modify the electronic communication, wherein
subsequent to being modified, the electronic communication comprises a pointer to a storage location storing the electronic copy of the document.
17. The non-transitory computer readable medium of claim 12 , wherein the program instructions are further executable to:
access a policy prior to searching a particular electronic communication, wherein
the policy indicates whether the particular electronic communication should be searched for any references to documents.
18. A system comprising:
a processor configured for detecting an archival of an electronic communication;
means for searching at least a portion of the electronic communication for a reference to a document, wherein
the document is not included in the electronic communication;
means for determining that a copy of the document is not currently being maintained as part of the archival of the electronic communication;
means for, in response to determining that the copy of the document is not currently being maintained as part of the archival of the electronic communication, automatically obtaining an electronic copy of the document from a location identified by the reference;
means for archiving the electronic copy of the document as an archived electronic copy of the document; and
means for retrieving the electronic communication and the archived electronic copy of the document at a time when the document is no longer available at the location identified by the reference.
19. The system of claim 18 , further comprising:
means for accessing a policy prior to searching a particular electronic communication, wherein
the policy indicates whether the particular electronic communication should be searched for any references to documents.
20. The system of claim 18 , further comprising:
means for locally storing the electronic copy of the document.
