    Abstract
    The rapid increase of the number of digital documents has caused the Internet users to be always up to date with the new documents. The providers of digital documents nowadays, who store information in the documents such as the titles, names of authors, years of publication, etc., use metadata. Various metadata can be used to store the information. The uniformity of using the metadata by following OAI PMH (Open Archives Initiative Protocol for Metadata Harvesting) principle can simplify the process of reading the digital data by machine and automatically handle the problem of different way of using the type of metadata. The main objective which was going to achieved was to produce the collection of distributed OAI-PMH metadata and to know the increase of acquisition of its metadata on the collection of single metadata. The collection of distributed metadata consisted of a computer as the coordinator and four computers as the collectors that were connected in a LAN (Local Area Network). This application was made by using java programming language. The communicating protocol between the collectors and the coordinators used RMI (Remote Method Invocation). Metadata were collected from 1460 repositories which were registered in www.openarchives.org within 10 hours. The results of the design of distributed metadata collection have fulfilled some aspects for a system so that it can be said distributed; that is, the user and resources, transparency, openness, and scalability. The acquisition of metadata can be increased by doing the additional parallel process.
     
    Peningkatan jumlah dokumen digital yang pesat telah menyebabkan para pengguna Internet harus tetap up-to-date dengan dokumen terbaru. Penyedia dokumen digital saat ini menyimpan informasi yang terkandung pada dokumen tersebut seperti judul, nama penulis, tahun penerbitan dan lain-lain menggunakan metadata. Berbagai jenis metadata dapat digunakan untuk menyimpan informasi tersebut. Penyeragaman penggunaan metadata dengan mengikuti kaidah OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting) dapat mempermudah proses pembacaan data digital oleh mesin sekaligus mengatasi masalah perbedaan penggunaan jenis metadata. Hal utama yang ingin dicapai adalah menghasilkan pengumpul metadata OAI PMH terdistribusi dan mengetahui peningkatan perolehan metadatanya terhadap pengumpul metadata tunggal. Pengumpul metadata terdistribusi terdiri dari satu buah komputer sebagai koordinator dan empat buah komputer sebagai pengumpul yang terhubung di dalam satu jaringan LAN (Local Area Network). Aplikasi ini dibuat menggunakan bahasa pemrograman java. Protokol komunikasi antara pengumpul dan koordinator menggunakan RMI (Remote Method Invocation). Metadata dikumpulkan dari 1460 repositori yang terdaftar di www.openarchives.org selama 10 jam. Hasil rancangan pengumpul metadata terdistribusi telah memenuhi beberapa aspek untuk sebuah sistem agar dikatakan terdistribusi yaitu pengguna dan sumber daya, transparansi, keterbukaan dan skalabilitas. Perolehan metadata dapat ditingkatkan dengan melakukan penambahan proses paralel.
