  2. 2. Abstract  In  liBle  more  than  two  decades  the  World  Wide  Web  has  passed  through  an  amazing  development.  As  a  rapidly  increasing  informa4on  medium  it  has  become  an  integral  part  of  our  daily  lives.  This  development  equally  affects  personal  and  commercial  environments  in  our  informa4on  oriented  society.  From  its  original  purpose  to  display  linked  documents  the  Web  evolved  towards  a  fully-­‐fledged  plaOorm  powering  rich  applica4ons  and  services.  The  technological  influence  is  broadly  no4ceable  on  many  different  device  types.  There  is  barely  a  new  connected  device  introduced  that  is  not  equipped  with  an  Web  browser  or  provides  access  to  Web  based  offerings.  Paired  with  plaOorm  heterogeneity  and  u4liza4on  of  advanced  device  capabili4es  new  opportuni4es  arise  for  exci4ng  applica4ons  in  this  seRng.  But  to  handle  this  diversity  service  providers  and  applica4on  developers  are  faced  with  fundamental  challenges  like  the  secure  end  device  to  end  device  communica4on  and  privacy  preserving  service  and  resource  accesses.  This  is  the  star4ng  point  for  the  webinos  project.  webinos  delivers  an  open  source  plaOorm  that  interconnects  users  devices  securely  and  allows  Web  technologies  based  applica4ons  to  run  and  use  services  and  resources  across  different  domains  like  mobile,  desktop,  home  media,  in-­‐car  infotainment  and  internet  of  things  (IoT).  Taking  the  current  realiza4on  of  the  webinos  concepts  for  the  Android  plaOorm  as  an  example,  shows  how  interoperability  with  other  device  types  and  plaOorms  can  be  fostered  and  how  mul4-­‐screen  applica4on  development  can  be  eased.     webinos – clearly connected 2

  16. 16. Developing  a  webinos  app  3-­‐steps  process  overview  1.  Start  realizing  your  app  idea  using  well  known  Web  technologies.  2.  Decide  which  services  and  resources  you  would  like  to  use  by  selec4ng  form  the   provided  webinos  APIs     (http://dev.webinos.org/specifications/api/).     Implement  against  an  abstract  device,  that   comes  with  all  proper4es  provided  by  all   physical  devices.  3.  Package    (http://www.w3.org/TR/widgets/)  the  applica4on  and  publish  it  on  apps  stores   (example:  https://webinos.fokus.fraunhofer.de/ )  or  on  a  Web  site.  Downloading  this   applica4on  will  allow  for  installa4on  and  execu4on  on  the  device.  LaBer  even  in   local  peer  network  without  internet  connec4vity.   webinos – clearly connected 16

  19. 19. node.js  on  Android  por2ng  webinos  •  Android  chosen  as  first  mobile  plaOorm  to  port  webinos  to,  reasons:   –  Accessible  embedded  plaOorm   –  Broad  range  of  interes4ng  data  sources  (sensors)  and  actuators   –  Not  limited  to  smartphones  only  (Android  based  home  media  equipment,  tablets)  •  Most  of  the  webinos  core  components  (in  par4cular  PZP)  are  implemented  in  node.js   –  Problem:  the  node.js  interpreter  cannot  run  on  Android  out-­‐of-­‐the-­‐box   –  Solu2on:  the  interpreter  has  been  build  as  library  and  integrated  in  java  run4me   –  Result:  the  interpreter  is  deployable  on  non-­‐rooted  devices    •  A  Java  Bridge  was  developed  to  access  the  Java  plaOorm  from  node.js.  This  made  implementa4on  in  Java   plus  interac4on  with  the  unchanged  PZP  code  possible  à  portability  •  For  more  informa4on  visit  Paddy  Byers  github  page  on  the  anode  project:     https://github.com/paddybyers/anode/wiki   webinos – clearly connected 19 Partly based on material of P.Byers
