Digital Object Memory

A digital object memory ( Dome for Digital Object Memory) is a data storage, are collected in the continuously all relevant information about an actual physical object. By linking digital information with physical objects such an object memory forms a basic building block for the Internet of Things

For use digital Objektgedächtnisse each physical objects must be uniquely identified by an identifier. The identifier must be machine-readable attached to the objects. Are usual one or two dimensional barcodes (eg a QR code or a data matrix code ) or radio-based RFID and NFC tags. These codes or tags provide a cost effective solution, but require a more complex infrastructure for data management.

Active digital Objektgedächtnisse

In addition to digital Objektgedächtnissen which consist exclusively of a passive memory, include active digital Objekgedächtnisse ( Adome ) full-fledged computer. In terms of a cyber - physical system ( CPS) this Objektgedächtnisse can be equipped with the following hardware:

  • Microprocessor,
  • Memory,
  • Micro sensors,
  • Positioning blocks
  • Radio modules to connect to the Internet,
  • Optional actuators,
  • Its own power supply or energy - harvesting unit

Software side is common feature:

  • Memory management functions,
  • Server processing components,
  • Optional sensor fusion modules,
  • Process processing components,
  • Communication interfaces,
  • User interface,
  • And security modules.

Active Objektgedächtnisse allow object-related processing, such as condition monitoring, data analysis or cleaning of memories to be able to perform directly on the object itself. In addition to purely passive and active memories, there are hybrid forms, which can for example perform simple operations directly on the object and complex operations can be swapped out in the surrounding infrastructure, both components of the memory will remain in sync.

Digital Product Memory

Digital product (DPG ) are a subset of the digital Objektgedächtnisse; they include the memories of artifacts that have been made ​​or that were at least deliberately produced. Examples are transport containers, works of art and rare natural objects such as marbles or lumps of gold, which were not produced by industry, but are still monitored for specific applications within the meaning of Life Logging.

Semantic Product Memory

Semantic Product Memories ( SemProM - for Semantic Product Memory) go one step further and provide a machine- understandable description ihreres content based on technologies of the Semantic Web. Have no explicit memories, semantic markup, only proprietary software modules can read the stored information. In contrast, semantic memories of any software can be interpreted, has the access to the semantic descriptions of epistemological primitives and corresponding ontologies.

Object Memory Model

In the context of Object Memory Modeling Incubator Group, as part of the W3C Incubator Activities, a structure format for Objektgedächtnisse was developed. The structural format allows static and event-based data from indidviduellen physical artifacts (ideally over the entire life span) to store and thus acts as a model for object memory data. The so-called Object Memory Model ( OMM) uses a block - based approach to the memory divided into groups, each containing coherent object-related information. Each block consists of the actual user data (payload ) and a set of metadata that describes the payload of the block.

SemProM

The SemProM ( Semantic Product Memory) project, funded by the Federal Ministry of Education and Research ( BMBF), uses so-called smart labels to give products a digital memory and thus be able to offer intelligent applications along the product life cycle chain. The integration of sensors integrated in the production process transparent relationships and supply chains as well as influences are traceable through the environment. The manufacturer is supported by and the consumer gets better information about the product.

RES -COM

The project RES -COM ( resource conservation through context-enabled M2M communications ), funded by the Federal Ministry of Education and Research, is engaged in the development of technologies for proactive resource conservation based on communication between machines (M2M ), with interfaces, protocols and data model are considered. The project seeks to promote the integration of distributed and active components and with a defined interaction to complement existing, centralized structures in the industry with active digital Objektgedächtnissen.

ADiWa

The project ADiWa (Alliance Digital Product Flow ), funded by the Federal Ministry of Education and Research, makes the great potential of information from the Internet of Things for business-relevant workflows, which can be strategically planned and influenced available. For the connection of objects of the real world, the results from the project partners SemProM be used. ADiWa it primarily deals with business processes that can be influenced by information from the real world and controlled.

The project Smart Products, funded by the 7th Framework Programme of the European Union, developed the scientific and technological basis for the construction of intelligent products ( Smart Products ) with embedded proactive knowledge. Such smart products help customers, designers and workers with the ever-growing complexity and diversity of modern products to keep pace. These products promote such proactive knowledge for communication and cooperation with the people of other products and the environment. The project thereby focuses on small devices with limited memory and therefore requires an efficient storage mechanism. Furthermore, the project will optimize the results for data exchange between different Smart Products in the form of a W3C Incubator Group on and apply.

Tales of Things and electronic Memory ( TOTEM ) is a three year Gemeinschaftaprojekt between five universities in the United Kingdom of Great Britain. The project goal is to research the impact of technologies of the Internet of things to the design of novel forms of large memory-based systems. While the influences of the Internet of Things for the management of supply chains and for the management of resource consumption and discussed widely accepted, the aspect of personal and social memories has only slightly low. While more and more products are produced fitted directly in the production and monitoring in the life cycle, Tales of Things focuses on the possibility space of exploration of content on the Internet of Things, which are generated by users and correlated with physical objects in terms.

SmaProN

The project Smart Product Networks ( SmaProN ), funded by the Federal Ministry of Education and Research, explores the dynamic linking of intelligent products into bundles of products and product hierarchies, based on the already developed Tip'n'Tell architecture (for integration of distributed product information) and the product description SPDO model ( through the use of description languages ​​of the Semantic Web ).

RAN

The project RFID - based Automotive Network ( RAN), funded by the Federal Ministry of Education and Research, is engaged in the development of RFID-based hybrid control architectures and methods for estimating the value chain. The example of the automotive industry, a combined data management is being developed for the exchange of product-relevant information in a decentralized manner based on RFID tags. In addition, in central databases order-relevant information is stored. Such architectures allow the transport of product-related data over the physical object and real-time background systems.
