sui dati ci puoi costruire sopra

<!-- .slide: data-background="#0A2A34" -->
_"library as a platform"_
David Weinberger
--
<!-- .slide: data-background="#0A2A34" -->
* infrastruttura: servizi, dati, strumenti
* possibilità di sviluppare nuovi servizi
* creare _valore_ lasciando ad altri la possibilità di costruire sopra
--
<!-- .slide: data-background="#0A2A34" -->
biblioteche come piattaforme _aperte_
--
<!-- .slide: data-background="#0A2A34" -->
* essere _aperti_ a tutti
* dare accesso ad ogni pezzo di informazioni che possiedono: contenuti digitali, metadati, il loro utilizzo, interazioni sociali attorno
* abilitare nuovi prodotti e servizi creati da chiunque abbia un'idea
* integrare tutto ciò che la biblioteca sa attorno all'ecosistema della Rete
--
<!-- .slide: data-background="#0A2A34" -->
* servire una comunità basata su un territorio, o su un interesse
* visibile alle _persone_ e non solo agli sviluppatori
---
<!-- .slide: data-background="#eec803" -->
##API
--
<!-- .slide: data-background="#eec803" -->
"interagire, in tempo reale, con i dati di un sito o un servizio."
--
<!-- .slide: data-background="#eec803" -->
* tempo reale <!-- .element: class="fragment" data-fragment-index="1" -->
* dati aggiornati <!-- .element: class="fragment" data-fragment-index="2" -->
* selezione: prendo solo quello che mi serve <!-- .element: class="fragment" data-fragment-index="3" -->
* programmabilità <!-- .element: class="fragment" data-fragment-index="4" -->
* selezione: prendo solo quello che vuole il data provider <!-- .element: class="fragment" data-fragment-index="5" -->

<!-- .slide: data-background="#1a00ff" -->
##scarico del database
--
<!-- .slide: data-background="#1a00ff" -->
"tutti i dati, e subito"
--
<!-- .slide: data-background="#1a00ff" -->
* permette analisi specifiche e ad ampio raggio <!-- .element: class="fragment" data-fragment-index="1" -->
* non in tempo reale <!-- .element: class="fragment" data-fragment-index="2" -->
* complessità <!-- .element: class="fragment" data-fragment-index="3" -->

L'intero corpus citazionale è uno dei vantaggi competitivi dell'oligopolio editoriale in ambito accademico, perchè possono farci dell'analisi bibliometrica (es. _impact factor_).
--
<!-- .slide: data-background="#8900cd" -->
riappropriarsi del corpus citazionale è una strategia a lungo termine per l'open access.

<!-- .slide: data-background="#960847" -->
E coi dati _transazionali_?

<!-- .slide: data-background="#960847" -->
"chi ha letto cosa, e quando"

* _ranking_

>In a scarier version of the future, libraries get cut out of the process altogether and are rendered obsolete. If Amazon, Apple, Google, and the American Girl company become not just the discovery mechanisms but also the primary providers of recorded entertainment—the books my daughter wants to read, the movies my son wants to watch, probably all the music they want to listen to—what place will be left for libraries?
John Palfrey, _Bibliotech_, 2015, p.[71](http://babele.io/bibliotech#1091-94).
--
<!-- .slide: data-background="#960847" -->
>Many other people are working hard—frankly, often harder and more productively than the library community—on related problems. Technologists, publishers, authors, agents, business strategists—all are working on the same set of problems, from different angles, [...] only with a profit motive rather than the public interest as their driver. And they have much more capital and talent devoted to the task.
John Palfrey, _Bibliotech_, 2015, p.[161](http://babele.io/bibliotech#2468-74).
