Definitions
- the invention relates to a method for documenting a type configuration generated using a provided type library for a computing device, in particular of a motor vehicle, according to claim 1.
- the invention further relates to a computer program according to claim 9.
- the invention relates to an electronically readable data carrier according to claim 10.
- DE 10 2010 050 379 A1 shows a product line-based content management system and a corresponding method.
- the object of the present invention is to provide a method, a computer program and a data carrier through which the security or integrity of software updates, particularly in motor vehicles, can be made possible in a particularly advantageous manner.
- This object is achieved according to the invention by the subject matter of the independent patent claims. Advantages and advantageous refinements of the invention are specified in the dependent claims, the description and the drawing.
- a first aspect of the invention relates to a method.
- the method serves to document a type configuration generated using a provided type library for at least one computing device, which is a first computing device and/or at least one further computing device.
- the first computing device is a computing device of a network of computing devices for product line development.
- the at least one further computing device is in particular a computing device of a motor vehicle.
- the respective computing device is in particular an electronic computing device and in particular includes a processor.
- the respective computing device is therefore advantageously designed as a computer and/or for electronic data processing.
- the type library is, for example, an interface description for accessing a particularly publicly accessible data structure and/or subprograms for a third-party utility program.
- the utility program can, for example, be designed as a server, which could be used by the subprograms.
- a partial and/or complete type configuration can be created, which, for example, represents a basis for a distributed development ecosystem.
- the documentation method according to the invention includes several steps:
- a first version of the type library is provided by a first computing device.
- an identification value of the first version of the type library is stored in a distributed database.
- a first at least partial and/or in particular complete type configuration is generated based on the first version of the type library by the first computing device and/or a further computing device, for example the computing device of the motor vehicle.
- an identification value of the first type configuration is stored in the distributed database.
- the distributed database is in particular a distributed ledger, analogous to a distributed cash book, which is advantageously suitable for documenting the type library and/or the type configuration.
- a distributed ledger for example, includes a type of consensus process, so that manipulation of the identification values, which can be clearly assigned to the type configuration or the type library, can be excluded or can be made particularly difficult.
- the identification value of the first version of the type library is a value such as a hash value, through which the first version of the type library can be clearly identified and, in particular, changes to the type library, which would in particular lead to a new version, can be recognized. Changes to the type library would result in a different identification value.
- the respective identification value of the respective version of the type configuration is designed analogously.
- the first computing device can, for example, be a computing device of an authoring system for the type library (English: Type Library Authoring System).
- the further computing device can be, for example, a control device of a motor vehicle.
- an advantage of the invention is a concrete, automated and irreversible creation and/or updating of the concrete, first type library as well as the partial and/or complete type configurations derived therefrom.
- the distributed database which is designed in particular as a distributed ledger, tamper-proof documentation can be made possible and the basis for distributed development ecosystems is laid. Data protection and the protection of intellectual property can be taken into account in a particularly advantageous manner.
- the method according to the invention is also suitable for managing type configurations, as a method for specifying a type configuration, as a method for checking the integrity of a type library, as a method for creating a consistent type configuration, which For example, it can be used for over-the-air updates and as a method for certifying a type configuration.
- the invention is based on the knowledge that distributed ledger technologies could be suitable for documenting distributed development ecosystems in particular.
- the type configuration can result in a concrete expression of a previously generic development result, for example when developing the type library. It should be possible to include a variety of configuration or ordering options from the end user perspective of the motor vehicle, which must be covered in the development process and taken into account in the production/manufacturing process.
- type libraries can be built that take into account a variety of configuration and ordering options. Furthermore, it is known how partial type configuration and finally how complete type configurations can be derived from the type library.
- the method according to the invention allows the requirements for the type library and/or the type configuration to be met and operationalized in a distributed development ecosystem.
- the method according to the invention creates a possibility, in particular based on the distributed database, of using a particularly central type library in order to be able to create in particular consistent, partial and/or complete type configurations, which in turn can represent a basis for a distributed development ecosystem.
- a particularly central type library in order to be able to create in particular consistent, partial and/or complete type configurations, which in turn can represent a basis for a distributed development ecosystem.
- references that can be represented in particular by the identification values and each refer to the type library or to the type configuration can be stored in the distributed database, for example as a hash (value) or in addition to the hash.
- the actual source data and thus, for example, the source code of the type library and/or the type configuration can be stored, for example, in a separate database.
- the distributed database is operated using a consensus process.
- the database is distributed Ledger and especially trained as a blockchain.
- the consensus process can, for example, be a proof of work, such as proof-of-work, which can be provided by solving cryptographic puzzles.
- proof of shares such as proof-of-stack
- the computing devices involved in the distributed database such as the first computing device and the at least one further computing device, each have the opportunity to provide proof of shares and/or proof of work and thus agree on a clear, generally valid version of the respective identification value.
- a so-called proof of time and/or a proof of space can be provided.
- the respective type library and/or the respective type configuration are each stored in at least one further database.
- at least one of the computing devices holds storage space in which, for example, the source code of the type library and/or the type configuration is stored, in particular in a database structure.
- At least one of the databases and/or at least one of the computing devices is synchronized via the distributed database, with in particular at least one of the computing devices being part of a product line development (Software Product Line (SPL) Engineering).
- SPL Software Product Line
- a file exchange takes place between the individual computing devices and/or databases, with the distributed database regulating a data comparison, so that the databases or computing devices are each, in particular, jointly up-to-date and thus rely on a respective current version of the type library or a type configuration (can).
- Databases of a Software Product Line (SPL) Engineering can be advantageously synchronized using a distributed ledger or blockchain in order to achieve the necessary transparency or verifiability for certification and/or to improve decentralized software development.
- software that is based on the type library and/or the type configuration can be kept up to date in a timely manner in every computing instance or computing device and thus, for example, in the motor vehicle.
- a second version of the type library which is derived from the first version, is provided by the first computing device and/or a further computing device.
- an identification value of the second version of the type library is stored in the distributed database.
- a new version of the type library is provided, which is or will be further developed based on the first type library, for example its source code.
- the identification value that uniquely identifies the second version of the type library is now also stored in the distributed database. If the distributed database is a blockchain, for example, another block with the associated identification value is added to the database.
- additional steps are carried out: generating at least a second at least partial and/or complete type configuration based on the second version of the type library by the first computing device and/or a further computing device. Furthermore, an identification value of the second type configuration is stored in the distributed database.
- constant development of the content of the type library can mean that it should be updated and re-versioned regularly, for example daily.
- the method now has the advantage that a corresponding release process can preferably be designed in such a way that existing content of the type library is not deleted, but only new content is added.
- a deletion of a type library should only be permitted if there are no elements of the partial and/or complete type configuration derived from it and therefore no concrete product instances, for example of the motor vehicle, in the hands of the end user be touched. With the additional steps this can now at least be understood.
- elements of the partial and/or complete type configuration can or should only be deleted if no specific product instances, such as motor vehicles, are affected.
- all elements of the product line development to which the complete type configuration refers are relevant to documentation and therefore silification if they are to be future software updates for a motor vehicle.
- the method can be used to secure any changes to the type configuration particularly advantageously in a documented and therefore particularly permanent manner.
- the respective identification value is a reference value and/or a cryptographic hash value and/or the respective partial library or the respective type configuration are stored at least as part of the respective identification value.
- the respective identification value includes a reference value and/or a hash value and/or the type library or the type configuration.
- At least one of the computing devices provides a runtime environment through which the respective type library and/or type configuration can be executed.
- at least one of the computing devices which has access to the distributed database and is, for example, part of the motor vehicle, is designed so that software based on one of the type configurations, for example of a product line, can be used directly when the method is used in product line development. This has the advantage that software can not only be distributed quickly but also executed.
- a second aspect of the invention relates to a computer program which can be loaded directly into a memory of a computing device, with program means for carrying out the steps of the method according to the first aspect of the invention when the program is executed in the computing device.
- a third aspect of the invention relates to an electronically readable data carrier, with electronically readable control information stored thereon, which includes at least one computer program according to the second aspect of the invention and is designed such that, when using the data carrier and a computing device, it implements a method according to the first aspect of the Carry out invention.

- a complete type configuration vTK(X) is created according to step S3 by the complete type configuration service vTKS.
- the associated identification values are now stored in step S4.
- the sub-library TB(N) can now be further developed in terms of content and released in a new version N+1 as sub-library TB(N+1), with a type library service TBS (English: Type Library Service) from this point onwards the new version N1 of the type library TB N+1 is used for reading purposes, for example.
