The created modular platform could help in archaeological documentation and analysis. The developed custom-tailored plugins could make a valuable contribution to data exchange and boost data management and revision processes.  
The work of the BIMData and XEOLABS developers has been shown to be essential for sharing the source code of important graphical instruments. In this regard, the ARK-BIM platform could be considered a bridge between HBIM archaeological projects and the main account of BIMData (especially for the BCF option).  
Revisions and modifications of HBIM data were at the centre of the BIMData and ARK-BIM design; because online data sharing constitutes the final stage of most HBIM projects, revisions and accurate data management and validation are all daily operations that need to be addressed. The BCF option ensures these analyses and guarantees proficient collaborations among professionals, facilitating new revision strategies and relationships.  
The new platform can be also be shared through different accessing rules; thanks to the different IFC scopes and accessing rules available via BIMData tokens, the custom platform can be shared, depending on management privileges. In fact, IFC models can be shared by managing different scopes in order to lock or unlock possibilities (e.g., IFC read/write; BCF read/write). Through this filter process, a custom platform can be published in three ways (managing via Postman and tokens): for project managers (in charge of the project for data management, revisions, updates and validations); for active/invited users (revisions and updates); for a large community with a light environment and less specific features [3]. This possibility is fundamental for sharing models and semantic data (object-levels data) depending on users and level of interest, managing access privileges for project teams and other people [30].  
ARK-BIM, as for BIMData and other cloud BIM solutions, does not require expensive and specific hardware; only an updated web browser and a low/medium graphic adaptor (GPU) are required. Moreover, these cloud computing solutions offer a democratic approach to data analysis and exchange, drastically reducing costs and releasing users from hardware constraints [30]. At the same time, cloud/server BIM solutions provide real-time and on-demand access, which make it possible to increase productivity and project phases [24]. These are fundamental aspects for increasing accessibility and the ease of analyses. Web solutions and services generate huge benefits for data sharing and exchange, allowing real-time modifications in smart environments [3; 31; 32].  
Being a web-based solution, ARK-BIM is fully compatible with mobile devices (even if not yet optimized). Portability, not only for laptops, is a crucial aspect concerning accessibility of information [33]. Through mobile devices, IFC models and related data become consultable everywhere, thus avoiding the need for institutions and particular instruments, for example, laboratories and dedicated computers [3]. At the same time, first person spaces, such as AR, VR and game-like environments, could boost information access and involvement [34; 35; 36]; this aspect could be considered in a future version of ARK-BIM.  
In conclusion, thanks to the available source code and web development possibilities, a custom platform has been designed for Heritage and historical assets (Figure 22); archaeological information can be easily consulted and exchanged among project teams and collaborators. ARK-BIM is free to be utilized and implemented by the community. Source codes are available on the official website.
