Repurpose legacy file formats and outmoded data

Our information management specialists convert legacy data to new specifications and create required file types and establish or supplement file repositories and existing databases. DTB provides conversion services for customers requiring the accurate and fully audited transformation of unstructured, semi-structured, or fully-structured data from one standard or non-standard format to another.

Legacy Files Repurposed - Our Process

The STAGES of CONVERSION:

1) REVIEW and ANALYSIS: In this first stage, the source content is carefully analyzed by our information analysts. During this review, the analysts determine how the source information can be correlated to the new specification or format. The analysts pay special attention to such things as: repeating information elements, generated text features, graphics, file entities, hidden or conditional text, and special formatting characteristics. The result of this analysis is a conversion strategy which determines the best re-use methodology for these elements. They then draft a report which details the mapping of original source content to its new destination according to the customer’s specification or format.

2) TRANSFORMATION: The next stage in the process renders the original content into its new structure or format. DTB uses a conversion engine which bases its decisions on mark-up structure and mapping information prior to conversion. Using this information, the source file is disassembled, and its elements, attributes, and content are output in a series of file streams. Source content structure and available metadata are stored in a database for reexamination or reuse. The conversion engine applies the structure elements and writes the data to the new destination file(s) specification or format. The conversion generates required reports: content transferred, number of elements converted, the overall mark-up-to-content ratio for both source and destination formats, and other quality metrics. Metrics are saved for each converted file and this detailed information forms part of the audit trail for each converted document.

3) INSPECTION: This stage of the process involves a thorough quality inspection by DTB production specialists. They examine converted documents for:

  • Match to original content
  • Compliance to target specification/format
  • Handling of repeating elements
  • Generated text, graphics, file entities, hidden or conditional text, and special formatting characteristics

Unexpected deviations from the source content are flagged for correction and noted on a hard copy of the converted document.

4) CORRECTION: All changes made to the converted document are tracked historically in a database. This enables the converted content to be “rolled back” to earlier versions if necessary. We routinely perform in-process reviews with our customers and their clients to ensure that all expectations are met regarding the conversion project. We will explain all technical aspects of the process to the detail desired to meet our customers’ contract requirements.

We develop comprehensive databases for specific product applications. In addition, we employ Digital Asset Management (DAM) techniques to ensure that recurrences of the same or similar information for like applications are identified and resolved. Using DAM techniques eliminates costly redundancies in data development, sustainment, and assists in the configuration management process.
