Abstract

To support efficient integration of heterogeneous lifelog service, we have previously proposed and implemented a lifelog mashup platform consisting of the lifelog common data model (LLCDM) and the lifelog mashup API (LLAPI) to access the standardized data. The LLCDM has standardized columns which is application-independent. And it has application-specific data (i.e. JSON format text of API response of a lifelog service) in the <content> column as a plain text. But because the LLCDM repository is implemented using the relational database, we can’t access to the <content> column data directory, and select out a particular field of it via the LLAPI. To cope with these problems, we exploited the lifelog mashup platform with the document-oriented No-SQL database MongoDB for the LLCDM repository. And, we conduct a case study developing an application of retrieving Twitter’s posts involving URLs.
