What are Canonical Fields?
Upon upload, Everlaw automatically detects metadata fields that refer to the same underlying concept, and groups them together. For example, all variations of the custodian field (“Custodian”, “Custdn”, “CUST”, etc.) will be grouped into the “Custodian” field. Though this automatic grouping is performed for all fields in the database, particular attention is paid to approximately 40 of the most common metadata fields, determined through an empirical analysis of the types of metadata fields that appear in document sets. These 40 or so fields are referred to as canonical fields. The canonical fields are listed below:
|All Custodians||Date Modified||Languages|
|All Paths||Date Received||MD5 Hash|
|Application||Date Saved||Message ID|
|Attachment IDs||Date Sent||Original Filename|
|Attachment Names||Document Type||Original Path|
|Bcc||End Date||Produced From|
|Begin Family||End Family||SHA1 Hash|
|Confidentiality||File Path||Start Date|
|Date||Has OCR||Translation Of|
|Date Accessed||Hash Value|
|Date Created||In Reply To|
Grouped/Canonical Fields and Searching
For grouped canonical and noncanonical fields, only the group field or canonical name will be searchable. Similar to a metadata alias, searching a grouped or canonical field will search across all the fields grouped under that particular field name. This makes it much easier to search across documents with synonymous fields.
Seeing original fields in the review window
While looking at the metadata panel in the review window, you can see the original field name by hovering above the value for any displayed metadata field. For example, in the image below, the canonical “Date Created” field has replaced the original field name, “Created”.
