Need to extract abstract of a wikipedia page
by aditya srinivas 23 Nov '23

23 Nov '23

Hello, I am writing a Java program to extract the abstract of the wikipedia page given the title of the wikipedia page. I have done some research and found out that the abstract with be in rvsection=0 So for example if I want the abstract of 'Eiffel Tower" wiki page then I am querying using the api in the following way. http://en.wikipedia.org/w/api.php?action=query&prop=revisions&titles=Eiffel… and parse the XML data which we get and take the wikitext in the tag <rev xml:space="preserve"> which represents the abstract of the wikipedia page. But this wiki text also contains the infobox data which I do not need. I would like to know if there is anyway in which I can remove the infobox data and get only the wikitext related to the page's abstract Or if there is any alternative method by which I can get the abstract of the page directly. Looking forward to your help. Thanks in Advance Aditya Uppu

UploadWizard campaign info API format
by Brion Vibber 24 May '12

24 May '12

I'm adding an API module to retrieve UploadWizard upload campaign information, which we need for the upcoming mobile application for Wiki Loves Monuments. Essentially the app will include a very limited implementation of a couple steps of UploadWizard for things like license selection and filling the ID field and description, so we have one consistent set of configuration for both web upload (using UploadWizard) and mobile uploads (using the app). The change waiting review in gerrit: https://gerrit.wikimedia.org/r/#/c/7832/ If anybody's got a prime usage in mind for reading UploadWizard campaign data from the API and has recommendations for adjusting the output format (maybe for making the editing view more AJAX-y) please give a shout -- this is not final and we can adjust it. Currently it'll return XML like this: <?xml version="1.0"?><api> <uploadcampaign> <campaigns> <campaign name="wlm-es" id="2" isenabled="0" autoCategories="" autoWikiText="" defaultAlt="" defaultCategories="" defaultDescription="" defaultLat="" defaultLon="" defaultOwnWorkLicence="cc-by-sa-3.0" headerLabelPage="sdfsdf" idField="sdfafsdfd" idFieldInitialValue="" idFieldLabel="" idFieldLabelPage="" idFieldMaxLength="25" licensesOwnWork="cc-by-sa-3.0|cc-by-3.0|cc-zero" ownWorkOption="choice" skipTutorial="" thanksLabelPage="" tutorialHelpdeskCoords="27, 1319, 691, 1384" tutorialTemplate="Licensing_tutorial_$1.svg" tutorialWidth="720" /> </campaigns> </uploadcampaign></api> or JSON like this: { "uploadcampaign": { "campaigns": [ { "name": "wlm-es", "id": 2, "isenabled": 0, "autoCategories": "", "autoWikiText": "", "defaultAlt": "", "defaultCategories": "", "defaultDescription": "", "defaultLat": "", "defaultLon": "", "defaultOwnWorkLicence": "cc-by-sa-3.0", "headerLabelPage": "sdfsdf", "idField": "sdfafsdfd", "idFieldInitialValue": "", "idFieldLabel": "", "idFieldLabelPage": "", "idFieldMaxLength": "25", "licensesOwnWork": "cc-by-sa-3.0|cc-by-3.0|cc-zero", "ownWorkOption": "choice", "skipTutorial": "", "thanksLabelPage": "", "tutorialHelpdeskCoords": "27, 1319, 691, 1384", "tutorialTemplate": "Licensing_tutorial_$1.svg", "tutorialWidth": "720" } ] } } -- brion

OAuth
by Chris Steipp 24 May '12

24 May '12

Hello all, There's been a fair amount of discussion on the wikitech-l list about oauth, but I realized some people may be here that are not on that list so I'm cross-posting. Since api users are probably one of the most likely groups to use oauth, I wanted to make sure everyone here had a chance to give input on the requirements. We're collecting user stories here: http://www.mediawiki.org/wiki/OAuth/User_stories, and hoping to compile a list of requirements and priorities before the Berlin hackathon. So if you see any uses that are missing from that list, please add it. Or vote for any use cases there that are similar to cases you would use. If you have any projects currently that you would like to use oauth with, please post as many details as possible, so we make sure that the implementation covers as many use cases as we can. Thanks!

Problem with encoding in API answer when many parameters ?
by Nicolas Vervelle 14 May '12

14 May '12

Hi, Very recently (saturday ?) my application, WPCleaner<http://en.wikipedia.org/wiki/User:NicoV/Wikipedia_Cleaner/Documentation>, started to behave strangely (report on enwiki<http://en.wikipedia.org/w/index.php?title=User_talk%3ANicoV%2FWikipedia_Cle…> and frwiki<http://fr.wikipedia.org/w/index.php?title=Discussion_utilisateur%3ANicoV%2F…>), without any modfications on my side. I checked what was going on, and it seems that answers from the API have problems with accented characters, like "é". For example, this very long request<http://fr.wikipedia.org/w/api.php?prop=templates&action=query&titles=Acteur…>, gives the following result (see the strange characters instead of the é, è, ...) : <?xml version="1.0"?><api> <query> <pages> <page ns="0" title="Les Experts (sÃ©rie tÃ©lÃ©visÃ©e)" missing="" /> <page ns="0" title="Liste des Ã©pisodes des Experts" missing="" /> <page ns="0" title="ModÃ¨le discussion:Palette Les Experts" missing="" /> <page ns="0" title="Personnages rÃ©currents dans Les Experts" missing="" /> <page ns="0" title="SÃ©rie tÃ©lÃ©visÃ©e" missing="" /> <page ns="0" title="Wallace Langham" missing="" /> <page ns="0" title="Ã‰tats-Unis" missing="" /> <page pageid="43579" ns="0" title="Acteur" /> But if I reduce the number of pages in the titles= argument<http://fr.wikipedia.org/w/api.php?prop=templates&action=query&titles=Acteur…>, it works again correctly (the "Modèle discussion:Palette Les Experts" is correct, other pages also but below in the answer) : <api> <query> <pages> <page ns="0" title="Modèle discussion:Palette Les Experts" missing="" /> <page pageid="43579" ns="0" title="Acteur" /> <page pageid="4307505" ns="0" title="Albert Robbins" /> <page pageid="5539" ns="0" title="Anglais"> Any idea ?

Dear Team, I am planning to start a new website containing celebrities from different areas like in sports, movies and politics. For this I am planning to exract data from Wikipedia using API in XML or JSON format. Can someone send me Wikipedia API and the format of response I get? I am pretty much new to this type of technical stuff. I tried going through the document but could not understand much in detail. An example format will be of great use. Thanks in advance. Regards M.Krishna Kranth Team works means more We less Me.
