This post explores the structure of BARDSS and, in particular, how we envision the user interface which might be launched by the end of April, 2016. BARDSS is divided into two main domains: the data entry/administrator interface and the user, search, and visualization interface. The data entry is only accessible for those working in the project. It is used by the team in charge of extracting the data from the documents and migrating it to the software. The user interface has a main landing web-page with diverse sections. The most important tool in the user interface is the search tool. This is where users can do crossed search based on the fields already listed and that we already introduced to the readers in the last post.

This is how we migrate data from the documents to the data entry form or administrator interface (Fig. 1): In order to make everything faster, we divide the screen into two windows, one for the database entry section, and the other for the digitized copy of the baptismal records. It looks more difficult than it actually is. There are many predetermined field that we just need to click on to add the data. For example, if we click on gender, legal status or filiation , a tab open with the limited options for those fields. We just need to select one of them. Once a field is added, we can reuse it without needing to write it again. For example, in the field “African origin,” every time we find a new “African nation” we click on the icon (+) and add the new nation. This feature works in the same way for owner, priest, church, and location. Once added, everything is faster. Fields are reusable. If the conditions are favorable, the images are clear, and the calligraphy is not extremely complicated, we usually spend around three minutes to add a single baptismal record to the database. We can access to the list of every record we have added and we can edit them whenever we want (Fig. 2).

The user Interface: a work in progress

This is how we envision the user interface (Fig.3). The landing page will contain the basic information of BARDSS, but most important, the search tool. The section Using the Database offer to the users some instruction of how to navigate the site. This section will also contain the description of the fields. In particular, we want to highlight that some fields need to be approached carefully such as “African Nation” and “Race.” This section will also contain a glossary of historical terms that are usually used in the documents. Map and Images will contain some significative images related to slavery in places represented on BARDSS such as Brazil, Colombia, Cuba, and Florida. An interactive map will show the location of those parishes that show up on the site. About the Project is dedicated to acknowledging those institutions and individual contributors that have helped to make this project possible. It will also have some links to related projects such as the ESSS or the “Trans-Atlantic Slave Trade Database”. Finally, the Contribute will make possible for users working with baptismal records on slave societies to collaborate with our project. We have not decided yet what would be the best way to make possible this collaboration through an interactive method between collaborators and administrators.

The most important section in BARDSS is the search tool, this is the core of this project. The goal is that users can make different types of crossed search based on the fields contained in the database. There are two main ways to search in the database, by data categories or by text. Data categories are those fixed fields we used to move the information from the document to the database. The great majority of the fields from BARDSS could be considered “data categories.” Some examples are gender, origin, filiation, legal status, age category, etc. The text category refers to those fields that are mainly plain text, such as names of the owners, baptized individual, mother, father, etc. The left side of the side in the search section will contain a list of the data and the users just need to choose/filter to obtain the results. After the search, the results will show up in a table expandable columns containing the fields selected during the search. Based on the successful project, the “Trans-Atlantic Slave Trade Database,” BARDSS will make possible to the users to visualize their search. The results can be manipulated in the form of graphs, pie charts, and bar charts. Next section will show some of this features and some samples of the type of visualization users can expect from BARDSS.
