Indonesia OneSearch (onesearch.id) is a new online service launched by the National Library of Indonesia in 2015. It is a portal that enables the public to discover resources from various databases of partner institutions including higher educations, government and private institutions and agencies as well as public and school libraries, in just one simple interface. Indonesia OneSearch also integrates both OPAC and e-Resources services to allow users to search across all collections managed by the National Library.
The idea came up with the concerns about the unavailability of a portal that indexes all kinds of collections, especially scientific resources such as research articles, theses and dissertations as well as other grey literature works. The existing portals are either incomprehensive or inactive. Moreover, such portals are not mobile friendly because they were designed for desktop use only.

2. Collaboration: Metadata Harvesting and Interoperability
The goal of Indonesia OneSearch is to provide an integrated database from all libraries in Indonesia to allow users to get access to extensive information and knowledge resources. To make it happen, there are two key challenges: metadata harvesting and interoperability. One of the important strategies is by collaborating with partner institutions referred that will act as contributors of the portal. The National Library of Indonesia has decided to apply the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) as a method for metadata harvesting. Contributors that have not implemented OAI-PMH on their metadata are encouraged and assisted to do so. However, the schema used are usually different among the contributors depending on what library information system they utilize. To make them interoperable, the metadata need to be converted into National Library's own schema that basically developed from MARC. This is again where collaboration plays its role because to do such process, the National Library needs to install a mini PC device as a metadata converter on contributors' servers which is therefore an agreement has to be made beforehand.

3. Innovative Features
- Multi Contents: Indonesia OneSearch integrates resources in various formats including e-journals, e-books, research articles, theses, dissertations, reports and even multimedia collections such as audio, video and images.
- Multi sectors: Indonesia OneSearch is not designed only for libraries but also other information providers including archives and museums.
- Multi-platform Interoperability: The system allows all kinds of platforms and software that may be used by the contributors to interoperably work. It requires only an implemented OAI-PMH that serves as a protocol for seamless metadata harvesting.
- Single Search Form: Indonesia OneSearch provides users with a single search form that allows them to discover multi-format resources from various databases extensively.
- Integrated with OPAC and e-Resources Services: Indonesia OneSearch allows users to search across all collections managed by the National Library.
- Search Widgets: Contributing institutions can use provided search widgets to be embedded in their own websites.
- Full-text Search: Indonesia OneSearch also provides access to full-text resources if it is available in the source repositories.
- NLP-based Text Analysis: Indonesia OneSearch uses the Natural Language Processing (NLP) to analyze texts from both the metadata and the full-texts to allow users to scrutinize the contents of the texts.
- Knowledge Explorer: Indonesia OneSearch facilitates users not only to search for resources but also to explore various entities such as people, organizations, locations, activities, time, etc. contained within the metadata and the full-texts. They are allowed to seek for correlations between one entities to another, identify co-occurrence patterns, trends and perform any other analysis through Knowledge Explorer feature.
- Volunteers and Communities: As a form of collaboration to support the program, the National Library of Indonesia works together with a team of volunteers and communities who manage the integrated database repositories as well as carry out socializations in order to enhance the usability and expand the network.

4. Achievements and Future Plans
Since its launching less than 2 years ago, there have been 480 institutions joining the network with the total of 518 libraries and 3,281 repositories containing 3.5 million records which are mainly catalogues, e-journals and electronic theses and dissertations. Higher education institutions are the highest contributors with a total of 1.8 million records. Currently the program is implementing its second phase focusing on the analysis of full-text resources available in contributors' open access repositories by using the NLP technology. Next phase, starting in 2018, will be focusing on the development of plagiarism detection system prepared specifically for Indonesian language as most of the resources available are written in Indonesian language.
