Propuesta
Lo que se desea tener es una manera de poder conectar servicios a la información generada en CONABIO para esto proponemos generar un servicio de consulta que exponga la información que queremos. En esta implementación base consideramos que nuestros conjuntos de datos están relacionados y que cada uno de ellos es en algún sentido información atómica, esto es que cualquier proyección de la misma carece de relevancia.
Hay diversas maneras de generar este servicio de consulta, por ejemplo HATEOAS o GraphQL. Ambas maneras se encargan de proveer especificaciones para exponer y enlazar la información como nosotros buscamos hacerlo. En esta propuesta usaremos GraphQL, para esto definiremos el esquema de nuestros distintos tipos de datos para que sean implementados en el schema de GraphQL. Esta descripción de los datos puede ser consultada en los anexos Tipos de datos primitivos y Tipos de datos CONABIO.
Además de un bosquejo del esquema incial también se tomo la decisión de hacer la resolución de las consultas al servicio por medio de acceso compuesto, una breve discusión al respecto se puede leer en Resolución de búsquedas en GraphQL. Partiendo los distintos servicios conforme a nuestra propuesta de nodos de información.

Resolución de búsquedas en GraphQL
Se pueden identificar tres distintas maneras de proceder en la resolución de las búsquedas en GraphQL: mediante un API REST, accesando directamente a la información via la base de datos y un acceso compuesto.
Resolver las consultas usando un API REST es muy útil si se tiene los servicios ya generados para desplegar los datos, aunque esto implica mantener dos aplicaciones, el API REST y la capa de GraphQL. Una gran ventaja de implementar las consultas de esta manera es que los servicios REST pueden ser microservicios y con esto se podrían segmentar los responsables de los mismos.
Si en cambio se usa el desarrollo de la intefaz de búsqueda se hace sobre las bases de datos en donde se encuentra la información se tendrá que definir y matener un esquema el cual agrupe toda las caracteríticas de los distintos tipos de información que se quiera publicar. Claro que el rendimiento de la aplicación será el óptimos pero se vuelve complicado la separación de responsabilidades.
El acceso compuesto lo que significa es el de unir pequeños desarrollos en GraphQL, esto al igual que el acceso por REST implica la posibilidad de tener responsables de pequeños desarrollos. A diferencia de la implementación con REST la resolución de las consultas son delegadas a los pequeños desarrollos y no tienen que se implementadas en el desarrollo principal. Lo único que se desarrolla en la aplicación principal son las uniones de los distintos esquemas.
