In contrast, the creation of tools to assist users in the development of SPARQL queries is still in its infancy. In this system demo, we present the SPARQL Analysis and Manipulation (SPAM) tool, which provides help for the development of SPARQL queries. The main features of the SPAM tool comprise an editor with both text and graphical interface, as well as various functions for the static and dynamic analysis of SPARQL queries.<\/jats:p>","DOI":"10.14778\/2367502.2367547","type":"journal-article","created":{"date-parts":[[2014,6,24]],"date-time":"2014-06-24T12:17:57Z","timestamp":1403612277000},"page":"1958-1961","source":"Crossref","is-referenced-by-count":3,"title":["SPAM"],"prefix":"10.14778","volume":"5","author":[{"given":"Andr\u00e9s","family":"Letelier","sequence":"first","affiliation":[{"name":"PUC Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorge","family":"P\u00e9rez","sequence":"additional","affiliation":[{"name":"Universidad de Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Reinhard","family":"Pichler","sequence":"additional","affiliation":[{"name":"Technische Universit\u00e4t Wien"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sebastian","family":"Skritek","sequence":"additional","affiliation":[{"name":"Technische Universit\u00e4t Wien"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2012,8]]},"reference":[{"key":"e_1_2_1_1_1","first-page":"411","volume-title":"VLDB","author":"Abadi D.
