### Digital Manufacturing Platforms  
In the early stages of the digitization of the industry there were Remote Machine Monitoring systems (RMMS) that are machine manufacturer software products designed to allow their clients to monitor their shop floor equipment [35]. DMG Mori Seiki has been a pioneer with an RMMS solution called Mori Net that allowed customers to monitor their DMG Mori Seiki machines over a local network or the Internet. For non DMG MORI machines they developed a solution named Messenger that is based on MTconnect, a standard for accessing machine tool data [36; 37]. The advent of the Internet of Things in the industry sector pushed the adoption of sensor-based information collection to address their key problems related primarily to machine downtimes and process delays. This way, machine monitoring evolves towards condition monitoring, which is the practice of monitoring electrical equipment, usually with external sensors, in order to gather the required data for diagnosis. To achieve this goal, data acquisition systems and data loggers are used to monitor all kinds of industrial equipment and devices. A 2017 Research & Markets magazine study provides that the market for condition monitoring is almost $11 billion for factories and OEMs. Dell, Caterpillar, Microsoft, IBM, General Electric, and Siemens, among others, are industry leaders named in the study. Besides condition monitoring, more types of services and requirements, such as preventive maintenance, runtime and uptime measurement, energy monitoring or performance tracking are coming up and as results Digital Manufacturing platforms are being shaped to cover a broader scope. In this broader scope, the European Factories of the Future Research Association (EFFRA) that is a non-for-profit, industry-driven association is performing an important role in the digitization of manufacturing industry and digital manufacturing platforms. As an example of the activity under EFFRA's umbrella, the \"Connected Factories\" CSA (Coordination and Support Action) establishes a structured overview of available and upcoming technological approaches and best practices [38]. The project identifies present and future needs, as well as challenges, of the manufacturing industries. The digitization of manufacturing connects people, devices, machines and enterprises, and includes concepts such as 'Industrial Internet', 'digital manufacturing platforms', and the 'Internet of Things' (IoT). Moreover, the Connected Factories explores pathways to the digital integration and interoperability of manufacturing systems and processes and the benefits this will bring. Hence, Connected Factories will enhance the awareness among companies of the use of digital technologies in the manufacturing sector, but also provide them with expertise to make informed choices about technology and business models. Connected Factories will improve companies' understanding of the use of digital techniques in the manufacturing industry, and also provide them with expertise to make informed technology and company model decisions. Digital manufacturing platforms allow the provision of manufacturing services in a broad sense [39]. Digital platforms provide services that can be used for data collection, storage, processing, and delivery. These data describe the whole context which includes the product that is being manufactured, the manufacturing process, the production assets, the worker, and the entire value network. In general, the digital platform for manufacturing can provide any \"digital\" extension of functionalities for physical assets, through the adoption of ICT technologies. Digital platforms play a crucial role in enabling the application scenarios of digital manufacturing [40]. All services are aimed at optimizing manufacturing from different perspectives such as efficiency, availability, quality, performance, flexibility, etc. Digital platforms can be on premise, in the cloud or in a hybrid architecture.
