The new data we collect are a research paper about slave, a website about silk route map, and a website about a chronology of silk route. The research paper was written by Mrs. Sally McKee, who mentioned the data source of two thousand slave slaves were gathered from the State Archives of Venice between 1360-1499. These data were shown in tables with respect to “Number of Slave Sale Contracts by City,” “Number of Slave Sale Contracts by Decade,” “Origins of Slave Sold,” “Average Age of Slaves by Gender,” and “Average Price of Female and Male Slaves in Sale Contracts by Decade.” For such scarce data, this research paper is quite a good help.
Comparing to the data size of slave sales we can gather, silk is easier to find. Two websites are the new data source. The first website is mainly a map and history. From the map, we can construct the route in our website as shown in Figure 2. The most difficult part relies on the data storage which is presented in the next paragraph. The other website is talking about the chronology of silk route, which we can adopt some historical events corresponding to the time period the users choose. The two websites seem to have many valuable data about silk, however, there is no detail descriptions about the mapping of the routes and its corresponding time period.
Data Storing and updating
We use JSON to store and organize our routing data.City and routing information is stored as follows:

Our last task will be to write a PHP script to translate user input to JSON format, update the back-end JSON file, and then finally refresh the display.
Basically, we achieve the milestones which were set in the beginning of the project. Although, there are some discrepancy between the result and the original project proposal because of the scarcity of silk and slave sales. We still do our best to gather some useful information that can aid the users to realize the route of silk and slave sales as thorough as possible.
