    1 Executive Summary The LoCloud project is dedicated to providing services for cultural heritage institutions. These services support the easy ingestion of cultural heritage content into Europeana1. In addition, the services help content providers capture metadata and enrich the data in order to increase the potential semantic linkage of the data within the World Wide Web. It is one of the major aims of LoCloud to reduce technical, semantic and skills barriers for providing content, and therefore cloud technology is used and cloud-based services have been implemented for facilitating the aggregation of digital content from small and medium cultural institutions. This deliverable provides a summary status report of the microservices that have been developed for the LoCloud project. Microservices are small, lightweight software services that each perform a set of narrowly defined functions. The various services can be arranged in independently deployable groups and can communicate with each other via defined interfaces. The distributed architecture makes it easier to deploy new versions of services, and to scale the development. In the LoCloud project the development effort for the various services was organized around multiple development teams realizing five main groups of microservices. Among these services are geolocation enrichment tools, metadata enrichment and vocabulary services, historic place names and Wikimedia crowdsourcing services. These microservices can be used and combined as needed by the content providing institutions. All microservices have been implemented on virtual machines in a cloud testlab (using the OpenNebula cloud computing platform) and all services are also integrated in the LoCloud aggregation platform MORe2.

    Figure 1 shows some of the various possibilities for implementing and using the LoCloud microservices. A generic enrichment service was designed that integrates the microservices into the MORe aggregator. Within the platform, users can choose which services should be called to enrich the metadata after transformation, or they can choose to capture data from selected Wikimedia resources. Besides using the services in the MORe aggregation facility, it is possible to implement individual microservices in a local cataloguing application through the available APIs of the services. Some of the LoCloud microservices have even been deployed as dedicated online tools. Among these are the geolocation, vocabulary and historic place names applications. The LoCloud cloud-based SaaS3 services serve the cultural heritage community in many ways. The enrichment services help to improve data quality for the content providers and Europeana. The data capturing service allows re-use of already existing online cultural content and allow its proper ingestion into Europeana. The scalability and various options for deploying and using the microservices help tailor the services offered for cultural heritage institutions, and to meet their needs and capacities.

    2 Introduction

    2.1 Purpose of this document This consolidated report provides an overview on the current status of the microservices available through LoCloud for public and professional consumption. Five different types of microservices have been developed and each microservice is described in detail in the following deliverables:

    D3.2 Geolocation Enrichment Tools D3.3 Metadata Enrichment D3.4 Vocabulary services D3.5 Historic place names service D3.6 Wikimedia and crowdsourcing

    The deliverables may be downloaded from the LoCloud project website at: http://www.locloud.eu/Resources/Deliverables. A first version of each service was developed and the implementation up to the end of August 2014 is described in the deliverables listed above. From September to November 2014, LoCloud content providers and technical partners tested the microservices. Test results and recommendations have been gathered and the se
