While the publication of Linked Data has become increasingly common, the process tends to be a relatively complicated and heavy-weight one. Linked Data is typically published by centralized entities in the form of larger dataset releases, which has the downside that there is a central bottleneck in the form of the organization or individual responsible for the releases. Moreover, certain kinds of data entries, in particular those with subjective or original content, currently do not fit into any existing dataset and are therefore more difficult to publish. To address these problems, we present here an approach to use nanopublications and a decentralized network of services to allow users to directly publish small Linked Data statements through a simple and user-friendly interface, called Nanobench, powered by semantic templates that are themselves published as nanopublications. The published nanopublications are cryptographically verifiable and can be queried through a redundant and decentralized network of services, based on the grlc API generator and a new quad extension of Triple Pattern Fragments. We show here that these two kinds of services are complementary and together allow us to query nanopublications in a reliable and efficient manner. We also show that Nanobench makes it indeed very easy for users to publish Linked Data statements, even for those who have no prior experience in Linked Data publishing.
虽然关联数据的发布已变得越来越普遍，但这个过程往往相对复杂且繁重。关联数据通常由中央实体以较大数据集版本的形式发布，其缺点是存在一个以负责发布的组织或个人为形式的中央瓶颈。此外，某些类型的数据条目，特别是那些具有主观或原创内容的数据条目，目前不适合任何现有数据集，因此更难发布。为了解决这些问题，我们在此提出一种方法，即使用纳米出版物和分散的服务网络，让用户能够通过一个简单且用户友好的界面（称为Nanobench）直接发布小型关联数据声明，该界面由本身作为纳米出版物发布的语义模板提供支持。发布的纳米出版物可通过加密进行验证，并可基于grlc API生成器和三元模式片段的新四元扩展，通过冗余且分散的服务网络进行查询。我们在此表明，这两种服务是互补的，共同使我们能够以可靠且高效的方式查询纳米出版物。我们还表明，Nanobench确实让用户非常容易发布关联数据声明，即使对于那些此前没有关联数据发布经验的用户也是如此。
