The purpose of this document is to outline standards for production of electronically stored information in discovery. The intent is for these standards to be easily communicated by attorneys at a meet and confer by referring to the category of production. The following definitions are provided regarding the forms of production (See the EDRM Production Guide for further clarification on the forms of production):
- Native Format – Files are produced in the format in which they were originally created (Example: .docx produced in .docx; .pdf produced in .pdf, etc.)
- Near-Native Format – Files are extracted or converted into another searchable format (Example: e-mails produced in .htm, .mht, or .rtf; Databases produced in .txt or .csv format)
- Image (Near Paper) Format – Electronic files are converted to image format or paper is scanned to image format
- Paper – Electronic files are printed to paper or paper files remain in paper format
The categories of production identified below include A, B, C, D and E. The descriptions of the standards are followed by a Quick Guide to Components of Productions A-D, a chart containing the Characteristics of Productions A-D and a chart containing the required metadata and other information fields. In addition to agreeing to one of these standards, the requesting party should tell the producing party which review tool they will be using. This information is needed to properly identify the components and formats required to successfully load the information into a review tool.
A. Native/Near-Native Production
E-mail, databases and proprietary files are produced in a near native format. Attachments and loose files are produced in native format. Only files requiring redaction are tiffed. Includes searchable text for redacted files.
- Each native /near-native file name matches the DocID. (I.e. DocID = ABC0000123; Filename = ABC0000123.doc for MS Word document.)
- Each searchable native/near native file has an extracted text file in .txt format named with the DocID of the corresponding file. Each non-searchable file containing text has a multipage OCR text file named with the DocID of the corresponding file. (I.e. DocID = ABC0000123; Filename = ABC0000123.txt.)
- Each file requiring redaction has group IV single page tifs. Each file requiring redaction has a unique bates number applied to images matching the DocID or Bates number. The same number may be applied to each page within a document or the numbers can increment by page.
- OCR for redacted files in multipage .txt format. Each file named the same as the DocID/Bates number of the corresponding document. (I.e. Image Filename = ABC0000123.tif; OCR Filename = ABC0000123.txt.)
- Load file(s) for native/near-native, images, extracted text and OCR files in EDRM xml or common format such as that required by Concordance or Summation.
- Data file including, at a minimum, the standard EDRM extracted metadata and other information fields to the extent they exist (see chart below). This data may be included in load file or produced as a separate text delimited file.
B. Image (Near-Paper)/Native/Near-Native Production
Most files are converted to image format (tif, pdf, etc.) with the exception of files like MS Excel that are not usable in image format and/or paper scanned to image format and OCR’d. Includes searchable text for redacted files.
- Most Native/near native files are converted to group IV single page tif. Each file has a unique bates number applied to images matching the DocID or Bates number.
- Each searchable native/near native file has an extracted text file in .txt format named with the DocID of the corresponding file. Each non-searchable file containing text has a multipage OCR text file named with the DocID of the corresponding file. (I.e. DocID = ABC0000123; Filename = ABC0000123.txt.)
- Spreadsheets and files that are not usable in .tif format are produced in native or near-native format and named the same as the Doc ID. (I.e. DocID = ABC0000123; Filename = ABC0000123.xls for MS Excel document.)
- OCR for redacted files in multipage .txt format. Each file named the same as the DocID/Bates number of the corresponding document. (I.e. Image Filename = ABC0000123.tif; OCR Filename = ABC0000123.txt.)
- Load file(s) for native/near-native, images, extracted text and OCR files in EDRM xml or common format such as that required by Concordance or Summation.
- Data file including, at a minimum, the standard EDRM extracted metadata and other information fields to the extent they exist (see chart below). This data may be included in load file or produced as a separate text delimited file.
C. Image Production
All files are converted to image format (tif, pdf, etc.) and/or paper is scanned to image format and OCR’d. Includes searchable text for redacted files.
- All Native/near native files are converted to group IV single page tif. Each file has a unique bates number applied to images matching the DocID or Bates number.
- All images are black & white except for those that require color for interpretation. Color images are produced in .jpg format unless otherwise agreed.
- Container files such as .zip or .rar may be converted to .tif format with a table of contents or referenced in the “folder” field containing the path to the original native file as it existed at the time of collection.
- Each searchable native/near native file has an extracted text file in .txt format named with the DocID of the corresponding file. Each non-searchable file containing text has a multipage OCR text file named with the DocID of the corresponding file. (I.e. DocID = ABC0000123; Filename = ABC0000123.txt.)
- OCR for redacted files in multipage .txt format. Each file named the same as the DocID/Bates number of the corresponding document. (I.e. Image Filename = ABC0000123.tif; OCR Filename = ABC0000123.txt.)
- Load file(s) for image files, extracted text and OCR in EDRM xml or common format such as that required by Concordance or Summation.
- Data file including, at a minimum, the standard EDRM extracted metadata and other information fields to the extent they exist (see chart below). This data may be included in load file or produced as a separate text delimited file.
D. Custom
- Images, Load File, Data file and no searchable text
- Images only
- Paper
- Other
E. On-line Production
Files presented for production via online review tool. Formats, fields, loads and exports to be negotiated on a case by case basis.
