As APIs proliferate, managing the constantly growing and evolving API landscapes inside and across organizations becomes a challenge. Part of the management challenge is for APIs to be able to describe themselves, so that users and tooling can use descriptions for finding and filtering APIs. A standardized labeling scheme can help to cover some of the cases where API self-description allows API landscapes to become more usable and scalable. In this paper we present the vision for standardized API labels, which summarize and represent critical aspects of APIs. These aspect allow consumers to more easily become aware of the kind of dependency they are going to establish with the service provider when choosing to use them. API labels not only summarize critical coupling factors, but also can include claims that require to be validated by trusted third parties.

LocWeb 2020 was the tenth workshop in the LocWeb workshop series at the intersection of location-based analytics and Web architecture and was held at The Web Conference, WWW 2020, on 21st April 2020. The focus was on Web-scale services and systems facilitating location-aware information access as well as on Spatial Social Computing on the Web. The LocWeb 2019 workshop had contributions ranging from urban location data analysis over geospatial open data access to worldwide media consumption patterns. The workshop and conference was intended to be held in Taipei, Taiwan, but was instead held as a virtual workshop since also The Web Conference itself moved to be an online-only event, due to the current pandemic. That also gave rise to a number of discussions around spatial models, online work modes, and current mitigation efforts. This report presents an overview of these discussions, after an introduction to the workshop theme and the individual contributions.

The Web as the world’s largest information system has largely settled on a solid foundation of HTTP-based connectivity, and the representation of User Interface (UI) information resources through a mix of HTML and scripting. In contrast, the similarly rapidly evolving “Web of Services” is still based on a more diverse and more quickly evolving set of approaches and technologies. This can make architectural decisions harder when it comes to choosing on how to expose information and services through an Application Programming Interface (API). This challenge becomes even more pronounced when organizations are faced with developing strategies for managing constantly growing and evolving API landscapes.This tutorial takes participants through two different journeys. The first one is a journey discussing API styles and API technologies, comparing and contrasting them as a way to highlight the fact that there is no such thing as the one best choice. The goal of this first journey is to provide an overview of how APIs are used nowadays in research and in industry. The second journey discusses the question of how to define an API strategy, which focuses both on helping teams to make effective choices about APIs in a given context, and on how to manage that context over time when large organizations nowadays have thousands of APIs, which will continue to evolve constantly.

It is our great pleasure to welcome you to the 8th International Workshop on Location and the Web (LocWeb2018) at WWW 2018. LocWeb 2018 will continue a successful workshop series at the intersection of location-based services and Web architecture. It focuses on Web-scale services and systems facilitating location-aware information access as well as on Spatial Social Behavior Analytics on the Web as part of social computing. The location topic is seen as a cross-cutting issue equally concerning information access, semantics and standards, social analysis and mining, and Web-scale systems and services. The workshop is an integrated venue where location and spatio-social aspects can be discussed in depth with an interested community. New application areas for Web architecture, such as the Internet of Things (IoT) and the Web of Things (WoT), will lead to increasingly rich and large sets of applications for which location is highly relevant as the connection to the physical world. Location has high importance in Web-based designs, and it continues to provide challenging research questions.

The Web is based on numerous standards that together make up the surface of the Web: By knowing and supporting those standards, problems can be solved in well-known ways. This general design pattern on the Web applies to APIs in the very same way as it does to the human Web: By using an (evolving) set of standards, API developers benefit by not having to reinvent the wheel, and developers benefit by the same problem being solved in the same way across a variety of APIs. The evolving set of standards for Web APIs can be regarded as a set of building blocks or vocabularies for API design. Web Concepts is a site (webconcepts.info) and a repository (github.com/dret/webconcepts) that can be used to manage how within organizations these building blocks are used, thus helping to establish a Web API design culture. The main idea of Web Concepts is to promote reuse of existing standards and technologies, and to therefore make it easier for teams to understand which options are available generally speaking, and maybe which ones are popular choices within their organization.

Structured syntax suffixes for media types allow other media types to build on them and make it explicit that they are built on an existing media type as their foundation. This specification defines and registers +json-seq as a structured syntax suffix for JSON text sequences.

The Web of Things is about extending the Internet of Things concept beyond the connection of things and considering issues like heterogeneity, scalability, and usability with respect to pervasive computing. The goal of this initiative is to reuse the architectural principles that made the Web successful and apply them to smart devices, thereby making real-world objects first-class citizens of the Web. The approach taken by the Web of Things initiative is to look at the problems and research issues that emerge when considering the interaction of heterogeneous devices within composite applications. Continuing the successful Web of Things workshop series, we further explored the use of technologies and principles at the core of the Web to provide methods for a seamless integration of physical devices. In particular, our goal in WoT 2016 was to foster discussions about how the Web architecture and its successful patterns can support semantic interoperability between devices and applications.
