Abstract

An integrated digital-analog archiving system can automatically initiate a migration process to move electronic documents to a media library. For each electronic document, the system may retrieve the electronic document from a digital data storage medium, extract metadata from the electronic document, determine size, orientation, and format of the electronic document, generate indicators for indicating the start and end of the electronic document to be stored on an analog data storage medium, generate an analog document identifier for identifying the electronic document on the analog data storage medium, generate a scaled image of the electronic document based on the size, orientation, and format of the electronic document, generate a text string based at least in part on the extracted metadata, and render the indicators, the analog document identifier, the scaled image of the electronic document, and the text string on the analog data storage medium.

First claim

What is claimed is:

1. An integrated digital-analog archiving system, comprising:
a processor;
a non-transitory computer readable medium; and
stored instructions embodied on the non-transitory computer readable medium and translatable by the processor to perform:
initiating a migration process to move a set of electronic documents to a media library, the set of electronic documents having associated metadata stored in a metadata database, the media library comprising a plurality of analog data storage media; and
for each electronic document of the set of electronic documents:
retrieving the electronic document from a digital data storage medium;
extracting metadata from the electronic document;
determining size, orientation, and format of the electronic document;
generating a first indicator for indicating a start of the electronic document on an analog data storage medium;
generating an analog document identifier for identifying the electronic document on the analog data storage medium;
generating a scaled image of the electronic document for the analog data storage medium based on the size, orientation, and format of the electronic document;
generating a text string based at least in part on the metadata extracted from the electronic document;
generating a second indicator for indicating an end of the electronic document on the analog data storage medium; and
generating an analog rendition of the electronic document including the first indicator, the analog document identifier, the scaled image of the electronic document, the text string, and the second indicator; and

verifying that the electronic document has not been modified during the migration process, the verifying including comparing the metadata extracted from the electronic document with the metadata stored in the metadata database;
wherein the stored instructions are further translatable by the processor for:
locating an analog data storage medium in the media library;
locating an analog rendition on the analog data storage medium;
capturing an image of the analog rendition;
processing the image of the analog rendition;
determining whether the image correctly reflects a requested document;
if the image does not correctly reflect the requested document, positioning the analog data storage medium and repeating the capturing, the processing, and the determining until a correct image that reflects the requested document is found;
capturing a final image of the analog rendition, the final image including an analog document and analog metadata located proximate the analog document on the analog data storage medium;
processing the final image of the analog rendition, the processing including generating an electronic file from the analog document and generating electronic metadata from the analog metadata;
adding the electronic metadata to the electronic file; and
returning the electronic file to service a request.

2. The integrated digital-analog archiving system of claim 1 , wherein the migration process is automatically initiated in response to a predetermined condition or setting being met.

3. The integrated digital-analog archiving system of claim 1 , wherein the digital data storage medium is embodied on a server machine communicatively connected to the media library over a network.

4. The integrated digital-analog archiving system of claim 1 , wherein the digital data storage medium is embodied on a server machine external or local to the integrated digital-analog archiving system.

5. The integrated digital-analog archiving system of claim 1 , wherein the analog data storage medium comprises a film, microfilm, microfiche, or paper.

6. The integrated digital-analog archiving system of claim 1 , wherein the stored instructions are translatable by the processor to perform:
generating a digital timestamp; and
adding an analog version of the digital timestamp to the text string so as to record a time when the scaled image of the electronic document is stored on the analog data storage medium.

7. The integrated digital-analog archiving system of claim 1 , wherein locating the analog rendition of the document on the analog data storage medium comprises detecting a start marker on the analog data storage medium.

8. The integrated digital-analog archiving system of claim 1 , wherein the electronic file is generated in Tagged Image File Format (TIFF).

9. The integrated digital-analog archiving system of claim 1 , wherein the analog metadata comprises a timestamp that records a time when the analog document was stored on the analog data storage medium and wherein the electronic metadata added to the electronic file comprises an electronic version of the timestamp.

10. The integrated digital-analog archiving system of claim 1 , wherein the analog document identifier comprises a bar code.

11. A computer program product for integrated digital-analog archiving, the computer program product comprising a non-transitory computer readable medium storing instructions translatable by a processor to perform:
initiating a migration process to move a set of electronic documents to a media library, the set of electronic documents having associated metadata stored in a metadata database, the media library comprising a plurality of analog data storage media; and
for each electronic document of the set of electronic documents:
retrieving the electronic document from a digital data storage medium;
extracting metadata from the electronic document;
determining size, orientation, and format of the electronic document;
generating a first indicator for indicating a start of the electronic document on an analog data storage medium;
generating an analog document identifier for identifying the electronic document on the analog data storage medium;
generating a scaled image of the electronic document for the analog data storage medium based on the size, orientation, and format of the electronic document;
generating a text string based at least in part on the metadata extracted from the electronic document;
generating a second indicator for indicating an end of the electronic document on the analog data storage medium; and
generating an analog rendition of the electronic document including the first indicator, the analog document identifier, the scaled image of the electronic document, the text string, and the second indicator; and

verifying that the electronic document has not been modified during the migration process, the verifying including comparing the metadata extracted from the electronic document with the metadata stored in the metadata database;
wherein the stored instructions are further translatable by the processor for:
locating an analog data storage medium in the media library;
locating an analog rendition on the analog data storage medium;
capturing an image of the analog rendition;
processing the image of the analog rendition;
determining whether the image correctly reflects a requested document;
if the image does not correctly reflect the requested document, positioning the analog data storage medium and repeating the capturing, the processing, and the determining until a correct image that reflects the requested document is found;
capturing a final image of the analog rendition, the final image including an analog document and analog metadata located proximate the analog document on the analog data storage medium;
processing the final image of the analog rendition, the processing including generating an electronic file from the analog document and generating electronic metadata from the analog metadata;
adding the electronic metadata to the electronic file; and
returning the electronic
