BAPTISMAL RECORDS DATABASE FOR SLAVE SOCIETIES

BARDSS structure: Data entry & User Interface


The BARDSS website is divided into two main sections: the behind-the-scenes data entry interface for project administrators and contributors, and the front-end search and visualization interface for users. Access to the data entry interface section is restricted to the BARDSS team. The user interface will consist of a homepage with different sections. The most important will be the search tool, with which users can conduct any type of simple or advanced search based on the fields already listed. The system allows users to then create tables, charts, and graphs with data resulting from the search.


The Data entry form - The administrator interface


This is how we add information to the database. Our computer screen is divided into two windows, one for the data entry form, and the other for the digitized baptismal records. With a larger workstation, it is even easier to simply use separate screens to view the archival documents and enter the appropriate information into the BARDSS system. We use this form to record all of the important content in the baptismal record. It looks more difficult than it actually is. There are many predetermined fields that a BARDSS team member can simply click on to record the data. For example, if we click on gender, legal status, or filiation, a tab opens with the available options for those fields. We then select one of them. Once a new data field is added BARDSS remembers the change, allowing us to select that option in the future without having to re-enter the field. For example, within the field “African Origin,” every time we identify a new "nation" in the documents we click on the icon (+) and add it to the BARDSS system. This feature works in the same way for individual owners, priests, churches, locations, and other information that reappears frequently. Once added, everything is faster. For instance, each time our newly-identified "nation" shows up in subsequent document we can simply click on it to record it as an attribute of the individual baptized in the record being added to BARDSS. The images are clear, and the calligraphy is not extremely complicated, we spend two to three minutes adding a single baptismal record to the database.



This second screenshot shows how the list of records look on the administrator interface. By clicking on each of these individual entries, we are able to edit their information.



the user interface: a work in progress


The homepage will contain basic information about BARDSS and, most importantly, the search tool. The section Using the Database offers users instructions for navigating the site. This section also contains descriptions of the fields. In particular, we want to caution users to approach some fields, such as “nation” and “race” with a critical mindset. This section will also contain a glossary of historical terms that are used frequently in the documents. Map and Images will contain images of interest to users exploring the history of slavery in places represented in BARDSS, such as Brazil, Colombia, Cuba, and Florida. An interactive map will show the location of those parishes from which we have drawn BARDSS data. About the Project is dedicated to acknowledging those institutions and individual contributors that have helped make this project possible. It will also contain links to related projects, such as the ESSSS or the "Trans-Atlantic Slave Trade Database." Finally, the Contribute will allow users working in one capacity or another with church archives in former slave societies to collaborate with our project. We have not yet decided the best way to enable this collaboration. The user interface should be launched this summer, 2016.



Search tools


The most crucial interface in BARDSS is the search tool; this is the core of the project. The goal is for users to be able to conduct different types of advanced and simple searches based on the fields contained in the database. Without a set of efficient and dynamic tools with which to filter and manipulate data, BARDSS would not be particularly useful. The BARDSS website contains a relatively straightforward advanced search tool, where users can select the variables by which they would like to filter the data and search the database for relevant information. There are three types of searches the user can do, which reflect two different kinds of data. The first is a text search, which allows one to search BARDSS by the names of baptized individuals, their family members, owners, and priests. Any name that appears in a baptismal record is searchable through BARDSS. The second is to search by standardized variables, like African nation, gender, legal status, location, and so on. These are descriptive fields that, unlike names, are confined a relatively regular, finite list of options. Baptismal entries record individuals as male or female, free or enslaved, Congo or Mandinga, and so on. Users can select which standardized variables they wish to use as search criteria, and query BARDSS in this manner. Finally, users can search by date of baptism. Unlike names and standardized variables, dates are sequential. This allows users to select a range of dates, and search BARDSS for results that fall within these parameters.

These search tools can be marshaled at the same time in an advanced search. For standardized variables, users can instruct the search engine to include only results that contain a chosen criterion, or, if a researcher is interested in locating records on people meeting a variety of different, but mutually exclusive criteria, they can request a search result that includes all of the potential results of interest. This is accomplished by the ability to designate a search criterion as an AND attribute, or an OR attribute. By selecting AND, users instruct the search engine to include ONLY results that satisfy that requirement. However, if a user is interested in searching results from, for example, two different churches in the same region of a country, they can select OR next to the churches they wish to search by. This allows users a degree of flexibility in searching the database.



Based on the success of the "Trans-Atlantic Slave Trade Database", BARDSS will allow users to visualize their findings. Once a user has conducted a search, BARDSS allows them to browse their results in the form of a list. With search results potentially in the thousands of individuals, this is not a particularly useful way to interact with the data. In order to take advantage of the database format, BARDSS contains four types of data manipulation and visualization tools. The first, and most flexible, is a table creator. This tool allows users to construct two-dimensional tables filled with quantitative data (totals, percentages, or averages). BARDSS also contains three different types of chart creation tools. The first is a line graph creator, in which users specify the independent and dependent variables and choose which type of data to graph. The second and third allow for the creation of bar graphs and pie charts to compare data. These tools are instrumental for making the enormous quantity of data contained in BARDSS comprehensible for users.
