Bigamy Dataset Description

How can this dataset be described e.g. content types and dates?       

The Prosecution Project is investigating the history of the criminal trial in Australia. As part of the project a web-based transcription tool for historical court records was created and documents are being transcribed by project team members and trained volunteers.

Case records in this data set have been entered by researchers or volunteer transcribers from scanned images of court registers in the custody of various state archives. Users should be aware that the records may contain transcription errors. Missing data (empty cell) usually indicates that information was missing in the original data source. In a small number of cases data in records have been accessed from additional sources (for example digitised newspapers or police gazettes).

The data sets available in this repository date from 1850 to 1922. The data refers to matters that were prosecuted within the respective jurisdictions of the six states as they currently exist (2018), which may be different from the jurisdiction formally in place for a particular offence in the early part of this period, e.g. prosecutions for Queensland (1850-1859) and Victoria (1850-July 1851) were formally under the jurisdiction of New South Wales during those years, but have been entered for Queensland and Victoria respectively.

The dataset  includes data drawn from original court registers, court calendars, trial briefs and police gazettes.  The Bigamy dataset is a combination of records drawn from the Victorian Supreme Court only at this stage.  Work is underway to expand this dataset to the other States.

Where is information about this dataset currently published online?

Information about this dataset is published on the Prosecution Project website: https://prosecutionproject.griffith.edu.au. Where possible, individual records have also been harvested via the OAI-PMH API by the originating archive / source and published on their website. eg: TAHO website

The bigamy dataset has been made published to the Australian Data Archive and is available in the Australian Historical Criminal Justice Data Collection. A sample notebook has also been created using this in the Tinker Studio github examples page located here.

What data structures are there e.g. tabular or document?

The data is in CSV format.

What metadata schemas are used to access the data e.g. local, DDI, ALTO or DC?

Local

How much time (and whose) is needed to compile the dataset ready for transfer?

In order to create this original dataset, the source documents need first to be located and digitised if not already done (by either a representative of the Prosecution Project or the originating source holder). These digitised items are then loaded onto the Prosecution Project’s server (by the Prosecution Project admin staff) to be transcribed by project team members and trained volunteers.

Once the records have been transcribed from originating source materials, a project team member uses the Prosecution Project tool to audit, correct, search, collate and extract the data to CSV file for all trials relating to Bigamy.

Once exported a manual combination of CSV files was required as different jurisdictions captured different metadata about a court proceeding.

In all it is estimated that 120  hours was required from a Prosecution Project administrator to curate the original dataset.

Subsequent work was done on the Prosecution Project application to enable researchers to combine data from different jurisdictions within the tool, thus reducing the amount of hours required to produce these datasets.

What is the scale of the dataset e.g. file numbers and size?

The dataset has 599 number of rows in the CSV file (as at September 2018) and is 135 Kb in size. It is expected that this will increase on a yearly basis until all data is publicly available.
