In the last two decades a number of popular open source frameworks have gained popularity: some notable ones in the open source arena are Joomla, Drupal and Wordpress (based on the PHP language) Liferay (based on the Java language) and Plone and Django CMS (based on Python).Ī different class of CMS, which we refer to as Data Content Management Systems (DCMS), is oriented toward the storage and distribution of open data and their metadata. This content can exist in a number of different forms (blog posts, articles, images, videos etc) and it can be typically created, reviewed and published by applying a revision workflow and can be shared with other users and/or group of users through a granular permission system.

Geospatial content management systemsĪ Content Management System (CMS) is a web application, which allows users to work within a collaborative environment to create and update digital content. In this section we will provide an overview on GeoCMSs and their background problem domain and related technologies. Harvard WorldMap is an open source Geospatial Content Management System (GeoCMS), containing a large number of geospatial datasets, which requires a framework to return to end users the most relevant and reliable results. We conclude the paper with some plans we have for the future to extend our research and the developed platform. We then discuss the implementation and the architecture of Hypermap and provide an overview of its benefits. After a review of the underlying technologies we provide a background of the use cases for these technologies at Harvard CGA, including a description of the architecture and the features of the WorldMap platform and why we decided to design and develop the Hypermap platform.

In this paper we first provide a description of the problem, which Hypermap aims to address.

Hypermap Registry is a free and open source platform, developed by the CGA of Harvard University, which tries to address this general problem: return relevant content from reliable web map services to users. It is therefore important to have a reliability indicator, which would help to identify and optionally exclude low quality services from returned results. Reliable web map services are those with a high percentage of correct responses to client requests. Reliability of web map services can be measured by periodically querying remote map layers. The same approach can be applied to return results from a registry of web map services.
#Mapproxy postgres software
The open source information retrieval software library Apache Lucene is currently used by a large number of web sites which require a powerful full-text searching mechanism.

In modern web sites, the problem of returning relevant content results to end users is addressed by using search engines frameworks. The registry should return quality content results to end users from web services which have a good reputation in respect of reliability. Metadata matches and content returned to a client querying a registry should be: 1) relevant, using a ranked search score 2) reliable, with respect to the web service availability.

This research approaches the problem from a new perspective focusing on content relevance and reliability. The second approach uses crawling algorithms which harvest search engine application programming interfaces (APIs), such as the Google search API, in order to obtain standard web map services endpoints. The first approach uses a centralized registry, which is updated by the service providers. In the past the problem of web service discovery has been addressed by primarily two approaches. One major challenge is to provide a way to discover and use geospatial content from these services, which is accessible by the general end user. Thousands of web map services deployed using open standards and protocols, are being made available to the general public, which consumes a large volume of geospatial data across many disciplines and geographic areas.
