The central purpose of this paper is to present a detailed description of a portal \u2014 IFPortal \u2014 that could provide a simple and appropriate way to aggregate, analyze, compare, and display information about e-government interoperability frameworks. Such a portal will enable the registration, search, visualization, analysis, and comparison of interoperability frameworks' content, structure and scope, thus allowing for the identification of similarities and differences among them. An IFPortal prototype, already developed, is also presented and may be accessed in order to exemplify the IFPortal concept.<\/p>","DOI":"10.4018\/ijwp.2014040102","type":"journal-article","created":{"date-parts":[[2015,2,6]],"date-time":"2015-02-06T13:55:03Z","timestamp":1423230903000},"page":"14-25","source":"Crossref","is-referenced-by-count":1,"title":["IFPortal"],"prefix":"10.4018","volume":"6","author":[{"given":"Luis","family":"Campos","sequence":"first","affiliation":[{"name":"Centro ALGORITMI, University of Minho, Braga, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Delfina","family":"Soares","sequence":"additional","affiliation":[{"name":"Centro ALGORITMI, University of Minho, Braga, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"ijwp.2014040102-0","doi-asserted-by":"publisher","DOI":"10.1504\/IJEG.2010.034095"},{"key":"ijwp.2014040102-1","unstructured":"CSTransform.
