Volunteered Geographic Information (VGI) is a version of crowdsourcing where volunteers produce, assemble and disseminate geographic information into websites. The citizens are encouraged to produce geographic information in web sites, as OpenStreetMap, using their own knowledge. VGI provides some advantages (e.g. generate detailed geographic information with low cost), nevertheless VGI data does not guarantee the quality. For that reason, there is a need to improve their quality. This is done through quality measures, indicators, approaches and the definition of a VGI protocol. The creation of a VGI protocol is important, because it drives the data collection of geographic data yielded by users. VGI protocol establishes a standardization for collaborative projects, improving the quality of citizen-derived geographical data sets and helping in the reuse of the protocol for other applications. It provides a definition of the processes that the citizen can do, right from the initialization in VGI platform, the description of the data model (as type of collected data and type of users), the methods of data collection, quality control, until the feedback from/to the users. Pauliceia 2.0 is a project whose aim is to develop a computational platform for manipulation of historical data collaboratively. Researchers contribute with these data and assist in quality control. In the Pauliceia 2.0 project, VGI is used to gather and share historical data resulted from researches provided by historians; and to produce historical geographical data sets of São Paulo city from 1870 to 1940. It is also used to collect other historical data, as the manual vectorization of ancient maps, collection of old addresses and the acquisition of historical photos associated to places. The main objective of this work is to define a VGI protocol for historical data and build a VGI Management Web Service (VGIMWS) based on the defined protocol, in the context of Pauliceia 2.0 project. This document presents a literature review, a stable version of the VGI protocol and of the web service for historical data. The protocol and VGIMWS were designed and built in the context of Pauliceia 2.0 project, however they are generic for historical data. So, they can be applied to other collaborative historical projects.
